iavf driver should set RSS LUT and key unconditionally in reset

In some circumstances, such as with bridging, it's possible that the
stack will add the device's own MAC address to its unicast address list.
If, later, the stack deletes this address, the driver will receive a
request to remove this address.
The driver stores its current MAC address as part of the VSI MAC filter
list instead of separately. So, this causes a problem when the device's
MAC address is deleted unexpectedly, which results in traffic failure in
some cases.
The following configuration steps will reproduce the previously
mentioned problem:
> ip link set eth0 up
> ip link add dev br0 type bridge
> ip link set br0 up
> ip addr flush dev eth0
> ip link set eth0 master br0
> echo 1 > /sys/class/net/br0/bridge/vlan_filtering
> modprobe -r veth
> modprobe -r bridge
> ip addr add 192.168.1.100/24 dev eth0
The following ping command fails due to the netdev->dev_addr being
deleted when removing the bridge module.
> ping <link partner>
Fix this by making sure to not delete the netdev->dev_addr during MAC
address sync. After fixing this issue it was noticed that the
netdev_warn() in .set_mac was overly verbose, so make it at
netdev_dbg().
Also, there is a possibility of a race condition between .set_mac and
.set_rx_mode. Fix this by calling netif_addr_lock_bh() and
netif_addr_unlock_bh() on the device's netdev when the netdev->dev_addr
is going to be updated in .set_mac.

When VFs are setup and torn down in quick succession, it is possible
that a VF is torn down by the PF while the VF's virtchnl requests are
still in the PF's mailbox ring. Processing the VF's virtchnl request
when the VF itself doesn't exist results in undefined behavior. Fix
this by adding a check to stop processing virtchnl requests when VF
teardown is in progress.

The userspace utility "driverctl" can be used to change/override the
system's default driver choices. This is useful in some situations
(buggy driver, old driver missing a device ID, trying a workaround,
etc.) where the user needs to load a different driver.
However, this is also prone to user error, where a driver is mapped
to a device it's not designed to drive. For example, if the ice driver
is mapped to driver iavf devices, the ice driver crashes.
Add a check to return an error if the ice driver is being used to
probe a virtual function.

All kernel devlink implementations call to devlink_alloc() during
initialization routine for specific device which is used later as
a parent device for devlink_register().
Such late device assignment causes to the situation which requires us to
call to device_register() before setting other parameters, but that call
opens devlink to the world and makes accessible for the netlink users.
Any attempt to move devlink_register() to be the last call generates the
following error due to access to the devlink->dev pointer.
[ 8.758862] devlink_nl_param_fill+0x2e8/0xe50
[ 8.760305] devlink_param_notify+0x6d/0x180
[ 8.760435] __devlink_params_register+0x2f1/0x670
[ 8.760558] devlink_params_register+0x1e/0x20
The simple change of API to set devlink device in the devlink_alloc()
instead of devlink_register() fixes all this above and ensures that
prior to call to devlink_register() everything already set.

Most users of ndo_do_ioctl are ethernet drivers that implement
the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware
timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP.
Separate these from the few drivers that use ndo_do_ioctl to
implement SIOCBOND, SIOCBR and SIOCWANDEV commands.
This is a purely cosmetic change intended to help readers find
their way through the implementation.

In SW DCB mode the packets sent receive incorrect UP tags. They are
constructed correctly and put into tx_ring, but UP is later remapped by
HW on the basis of TCTUPR register contents according to Tx queue
selected, and BW used is consistent with the new UP values. This is
caused by Tx queue selection in kernel not taking into account DCB
configuration. This patch fixes the issue by implementing the

When receiving a packet with multiple fragments, hardware may still
touch the first fragment until the entire packet has been received. The
driver therefore keeps the first fragment mapped for DMA until end of
packet has been asserted, and delays its dma_sync call until then.
The driver tries to fit multiple receive buffers on one page. When using
3K receive buffers (e.g. using Jumbo frames and legacy-rx is turned
off/build_skb is being used) on an architecture with 4K pages, the
driver allocates an order 1 compound page and uses one page per receive
buffer. To determine the correct offset for a delayed DMA sync of the
first fragment of a multi-fragment packet, the driver then cannot just
use PAGE_MASK on the DMA address but has to construct a mask based on
the actual size of the backing page.
Using PAGE_MASK in the 3K RX buffer/4K page architecture configuration
will always sync the first page of a compound page. With the SWIOTLB
enabled this can lead to corrupted packets (zeroed out first fragment,
re-used garbage from another packet) and various consequences, such as
slow/stalling data transfers and connection resets. For example, testing
on a link with MTU exceeding 3058 bytes on a host with SWIOTLB enabled
(e.g. "iommu=soft swiotlb=262144,force") TCP transfers quickly fizzle
out without this patch.

To avoid races between iavf_init_task(), iavf_reset_task(),
iavf_watchdog_task(), iavf_adminq_task() as well as the shutdown and
remove functions more locking is required.
The current protection by __IAVF_IN_CRITICAL_TASK is needed in
additional places.
- The reset task performs state transitions, therefore needs locking.
- The adminq task acts on replies from the PF in
iavf_virtchnl_completion() which may alter the states.
- The init task is not only run during probe but also if a VF gets stuck
to reinitialize it.
- The shutdown function performs a state transition.
- The remove function performs a state transition and also free's
resources.
iavf_lock_timeout() is introduced to avoid waiting infinitely
and cause a deadlock. Rather unlock and print a warning.

The iavf watchdog task overrides adapter->state to __IAVF_RESETTING
when it detects a pending reset. Then schedules iavf_reset_task() which
takes care of the reset.
The reset task is capable of handling the reset without changing
adapter->state. In fact we lose the state information when the watchdog
task prematurely changes the adapter state. This may lead to a crash if
instead of the reset task the iavf_remove() function gets called before
the reset task.
In that case (if we were in state __IAVF_RUNNING previously) the
iavf_remove() function triggers iavf_close() which fails to close the
device because of the incorrect state information.
This may result in a crash due to pending interrupts.

The solution is to not touch the adapter->state in iavf_watchdog_task()
and let the reset task handle the state transition.

i40e_config_vf_promiscuous_mode() calls
i40e_getnum_vf_vsi_vlan_filters() without acquiring the
mac_filter_hash_lock spinlock.
This is unsafe because mac_filter_hash may get altered in another thread
while i40e_getnum_vf_vsi_vlan_filters() traverses the hashes.
Simply adding the spinlock in i40e_getnum_vf_vsi_vlan_filters() is not
possible as it already gets called in i40e_get_vlan_list_sync() with the
spinlock held. Therefore adding a wrapper that acquires the spinlock and
call the correct function where appropriate.

Each i225 has three LEDs. Export them via the LED class framework.
Each LED is controllable via sysfs. Example:
$ cd /sys/class/leds/igc_led0
$ cat brightness # Current Mode
$ cat max_brightness # 15
$ echo 0 > brightness # Mode 0
$ echo 1 > brightness # Mode 1
The brightness field here reflects the different LED modes ranging
from 0 to 15.

Currently flex filters are only used for filters containing user data.
However, it makes sense to utilize them also for filters having
multiple conditions, because that's not supported by the driver at the
moment. Add it.

Use the flex filter mechanism to extend the current ethtool filter
operations by intercoperating the user data. This allows to match
eight more bytes within a Ethernet frame in addition to macs, ether
types and vlan.
The matching pattern looks like this:
* dest_mac [6]
* src_mac [6]
* tpid [2]
* vlan tci [2]
* ether type [2]
* user data [8]
This can be used to match Profinet traffic classes by FrameID range.

The Intel i225 NIC has the possibility to add flex filters which can
match up to the first 128 byte of a packet. These filters are useful
for all kind of packet matching. One particular use case is Profinet,
as the different traffic classes are distinguished by the frame id
range which cannot be matched by any other means.
Add code to configure and enable flex filters.

Pull networking fixes from Jakub Kicinski.
"Including fixes from bpf and netfilter.
Current release - regressions:
- sock: fix parameter order in sock_setsockopt()
Current release - new code bugs:
- netfilter: nft_last:
- fix incorrect arithmetic when restoring last used
- honor NFTA_LAST_SET on restoration
Previous releases - regressions:
- udp: properly flush normal packet at GRO time

subflow receive buffers longer than necessary, delaying MPTCP-level
ACKs
- ip_tunnel: fix mtu calculation for ETHER tunnel devices
- do not reuse skbs allocated from skbuff_fclone_cache in the napi
skb cache, we'd try to return them to the wrong slab cache
- tcp: consistently disable header prediction for mptcp
Previous releases - always broken:
- bpf: fix subprog poke descriptor tracking use-after-free
- ipv6:
- allocate enough headroom in ip6_finish_output2() in case
iptables TEE is used
- tcp: drop silly ICMPv6 packet too big messages to avoid
expensive and pointless lookups (which may serve as a DDOS
vector)
- make sure fwmark is copied in SYNACK packets
- fix 'disable_policy' for forwarded packets (align with IPv4)
- netfilter: conntrack:
- do not renew entry stuck in tcp SYN_SENT state
- do not mark RST in the reply direction coming after SYN packet
for an out-of-sync entry
- mptcp: cleanly handle error conditions with MP_JOIN and syncookies
- mptcp: fix double free when rejecting a join due to port mismatch
- validate lwtstate->data before returning from skb_tunnel_info()
- tcp: call sk_wmem_schedule before sk_mem_charge in zerocopy path
- mt76: mt7921: continue to probe driver when fw already downloaded
- bonding: fix multiple issues with offloading IPsec to (thru?) bond
- stmmac: ptp: fix issues around Qbv support and setting time back
- bcmgenet: always clear wake-up based on energy detection
Misc:

xfrmdev_ops
There are two pointers in struct xfrm_state_offload, *dev, *real_dev.
These are used in callback functions of struct xfrmdev_ops.
The *dev points whether bonding interface or real interface.
If bonding ipsec offload is used, it points bonding interface If not,
it points real interface.
And real_dev always points real interface.
So, ixgbevf should always use real_dev instead of dev.
Of course, real_dev always not be null.
Test commands:
ip link add bond0 type bond
#eth0 is ixgbevf interface
ip link set eth0 master bond0
ip link set bond0 up
ip x s add proto esp dst 14.1.1.1 src 15.1.1.1 spi 0x07 mode \
