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.

The current maximum RX ring size is defined assuming the RX jumbo ring
(aka aggregation ring) is used. The RX jumbo ring is automicatically used
when the MTU exceeds a threshold or when rx-gro-hw/lro is enabled. The RX
jumbo ring is automatically sized up to 4 times the size of the RX ring
size.
The BNXT_MAX_RX_DESC_CNT constant is the upper limit on the size of the
RX ring whether or not the RX jumbo ring is used. Obviously, the
maximum amount of RX buffer space is significantly less when the RX jumbo
ring is not used.
To increase flexibility for the user who does not use the RX jumbo ring,
we now define a bigger maximum RX ring size when the RX jumbo ring is not
used. The maximum RX ring size is now up to 8K when the RX jumbo ring
is not used. The maximum completion ring size also needs to be scaled
up to accomodate the larger maximum RX ring size.
Note that when the RX jumbo ring is re-enabled, the RX ring size will
automatically drop if it exceeds the maximum.

We currently store these page addresses and DMA addreses in static
arrays. On systems with 4K pages, we support up to 64 pages per
completion ring. The actual number of pages for each completion ring
may be much less than 64. For example, when the RX ring size is set
to the default 511 entries, only 16 completion ring pages are needed
per ring.
In the next patch, we'll be doubling the maximum number of completion
pages. So we convert to allocate these arrays as needed instead of
declaring them statically.

1PPS (One Pulse Per Second) is a signal generated either
by the NIC PHC or an external timing source.
Integrating the support to configure and use 1PPS using
the TSIO pins along with PTP timestamps will add Grand
Master capability to the 5750X family chipsets.
This patch initializes the driver data structures and
registers the 1PPS with kernel, based on the TSIO pins'
capability in the hardware. This will create a /dev/ppsX
device which applications can use to receive PPS events.
Later patches will define functions to configure and use
the pins.

During error recovery or hot firmware upgrade, the chip may be under
reset and the PHC register read cycles may cause completion timeouts.
Check that the chip is not under reset condition before proceeding
to read the PHC by checking the flag BNXT_STATE_IN_FW_RESET. We also
need to take the ptp_lock before we set this flag to prevent race
conditions.
We need this logic because the PHC now will stay registered after
bnxt_close().

It was pointed out by Richard Cochran that registering the PHC during
probe is better than during ifup, so move bnxt_ptp_init() back to
bnxt_init_one(). In order to work correctly after firmware reset which
may result in PTP config. changes, we modify bnxt_ptp_init() to return
if the PHC has been registered earlier. If PTP is no longer supported
by the new firmware, we will unregister the PHC and clean up.
This partially reverts:

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.

The current PTP initialization logic does not account for firmware
reset that may cause PTP capability to change. The valid pointer
bp->ptp_cfg is used to indicate that the device is capable of PTP

and free it if the firmware after reset does not support PTP.

The device needs to be in ifup state for PTP to function, so move
bnxt_ptp_init() to bnxt_open(). This means that the PHC will be
registered during bnxt_open().
This also makes firmware reset work correctly. PTP configurations
may change after firmware upgrade or downgrade. bnxt_open() will
be called after firmware reset, so it will work properly.
bnxt_ptp_start() is now incorporated into bnxt_ptp_init(). We now
also need to call bnxt_ptp_clear() in bnxt_close().

bnxt_half_open_nic() is called during during ethtool self test and is
protected by rtnl_lock. Firmware reset can be happening at the same
time. Only critical portions of the entire firmware reset sequence
are protected by the rtnl_lock. It is possible that bnxt_half_open_nic()
can be called when the firmware reset sequence is aborting. In that
case, bnxt_half_open_nic() needs to check if the ABORT_ERR flag is set
and abort if it is. The ethtool self test will fail but the NIC will be
brought to a consistent IF_DOWN state.
Without this patch, if bnxt_half_open_nic() were to continue in this
error state, it may crash like this:

Setting the EXT_ENERGY_DET_MASK bit allows the port energy detection
logic of the internal PHY to prevent the system from sleeping. Some
internal PHYs will report that energy is detected when the network
interface is closed which can prevent the system from going to sleep
if WoL is enabled when the interface is brought down.
Since the driver does not support waking the system on this logic,
this commit clears the bit whenever the internal PHY is powered up
and the other logic for manipulating the bit is removed since it
serves no useful function.

Trivial conflict in net/netfilter/nf_tables_api.c.
Duplicate fix in tools/testing/selftests/net/devlink_port_split.py
- take the net-next version.
skmsg, and L4 bpf - keep the bpf code but remove the flags
and err params.

Call bnxt_ptp_init() to initialize and register with the clock driver
to enable PTP support. Call bnxt_ptp_free() to unregister and clean
up during shutdown.

Setup the TXBD to enable TX timestamp if requested. At TX packet DMA
completion, if we requested TX timestamp on that packet, we defer to
.do_aux_work() to obtain the TX timestamp from the firmware before we
free the TX SKB.
v2: Use .do_aux_work() to get the TX timestamp from firmware.

If the RX packet is timestamped by the hardware, the RX completion
record will contain the lower 32-bit of the timestamp. This needs
to be combined with the upper 16-bit of the periodic timestamp that
we get from the timer. The previous snapshot in ptp->old_timer is
used to make sure that the snapshot is not ahead of the RX timestamp
and we adjust for wrap-around if needed.
v2: Make ptp->old_time read access safe on 32-bit CPUs.

From the bnxt_timer(), read the 48-bit hardware running clock
periodically and store it in ptp->current_time. The previous snapshot
of the clock will be stored in ptp->old_time. The old_time snapshot
will be used in the next patches to compute the RX packet timestamps.
v2: Use .do_aux_work() to read the timer periodically.

Add the clock APIs to set/get/adjust the hw clock, and the related
ioctls and ethtool methods.
v2: Propagate error code from ptp_clock_register().
Add spinlock to serialize access to the timecounter. The
timecounter is accessed in process context and the RX datapath.
Read the PHC using direct registers.

The Broadcom UniMAC MDIO bus from mdio-bcm-unimac module comes too late.
So, GENET cannot find the ethernet PHY on UniMAC MDIO bus. This leads
GENET fail to attach the PHY as following log:
bcmgenet fd580000.ethernet: GENET 5.0 EPHY: 0x0000
...
could not attach to PHY
bcmgenet fd580000.ethernet eth0: failed to connect to PHY
uart-pl011 fe201000.serial: no DMA platform data
libphy: bcmgenet MII bus: probed
...
unimac-mdio unimac-mdio.-19: Broadcom UniMAC MDIO bus
It is not just coming too late, there is also no way for the module
loader to figure out the dependency between GENET and its MDIO bus
driver unless we provide this MODULE_SOFTDEP hint.
This patch adds the soft dependency to load mdio-bcm-unimac module
before genet module to fix this issue.

The bnxt driver has rcu_read_lock()/rcu_read_unlock() pairs around XDP
program invocations. However, the actual lifetime of the objects referred
by the XDP program invocation is longer, all the way through to the call to
xdp_do_flush(), making the scope of the rcu_read_lock() too small. This
turns out to be harmless because it all happens in a single NAPI poll
cycle (and thus under local_bh_disable()), but it makes the rcu_read_lock()
misleading.
Rather than extend the scope of the rcu_read_lock(), just get rid of it
entirely. With the addition of RCU annotations to the XDP_REDIRECT map
types that take bh execution into account, lockdep even understands this to
be safe, so there's really no reason to keep it around.

Resetting software indexes in bcm4908_dma_alloc_buf_descs() is not
enough as it's called during device probe only. Driver resets DMA on
every .ndo_open callback and it's required to reset indexes then.
This fixes inconsistent rings state and stalled traffic after interface
down & up sequence.
