Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.
Use BUILD_BUG_ON in a couple ATM drivers.
In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is
in my opinion is quite an achievement. Hopefully this patch inspires
someone else to trim vsprintf.c more.

When a vNIC client driver requests a faulty device setting, the

Current behaviour of "mirred redirect" action (forward) offload is a bit
odd. For matched packets the action forwards them to the desired
destination, but it also lets the packet duplicates to go the original
way down (bridge, router, etc). That is more like "mirred mirror".
Fix this by using PBS type which behaves exactly like "mirred redirect".
Note that PBS does not support loopback mode.

The xilinx_emaclite uses __raw_writel and __raw_readl for register
accesses. Those functions do not imply any kind of memory barriers and
they may be reordered.
The driver does not seem to take that into account, though, and the
driver does not satisfy the ordering requirements of the hardware.
For clear examples, see xemaclite_mdio_write() and xemaclite_mdio_read()
which try to set MDIO address before initiating the transaction.
I'm seeing system freezes with the driver with GCC 5.4 and current
Linux kernels on Zynq-7000 SoC immediately when trying to use the
interface.
In commit 123c1407af87 ("net: emaclite: Do not use microblaze and ppc
IO functions") the driver was switched from non-generic
in_be32/out_be32 (memory barriers, big endian) to
__raw_readl/__raw_writel (no memory barriers, native endian), so
apparently the device follows system endianness and the driver was
originally written with the assumption of memory barriers.
Rather than try to hunt for each case of missing barrier, just switch
the driver to use iowrite32/ioread32/iowrite32be/ioread32be depending
on endianness instead.
Tested on little-endian Zynq-7000 ARM SoC FPGA.

xilinx_emaclite looks at the received data to try to determine the
Ethernet packet length but does not properly clamp it if
proto_type == ETH_P_IP or 1500 < proto_type <= 1518, causing a buffer
overflow and a panic via skb_panic() as the length exceeds the allocated
skb size.
Fix those cases.
Also add an additional unconditional check with WARN_ON() at the end.

In the current driver, the MTU is set to the maximum value
capable for the backing device. This decision turned out to
be a mistake as it led to confusion among users. The expected
initial MTU value used for other IBM vNIC capable operating
systems is 1500, with the maximum value (9000) reserved for
when Jumbo frames are enabled. This patch sets the MTU to
the default value for a net device.
It also corrects a discrepancy between MTU values received from
firmware, which includes the ethernet header length, and net
device MTU values.
Finally, it removes redundant min/max MTU assignments after device
initialization.

Even though the port autoselection is enabled by default on AM79C970A,
BNC/AUI port does not work because the link is always reported to be
down. The link state reported by the chip belongs only to the TP port
but the driver uses it regardless of the port used. The chip can't
detect BNC/AUI link state.
Disable port autoselection and use TP port by default to keep current
behavior (link detection works on TP port, BNC/AUI port does not work).
Implement ethtool autoneg, port and duplex configuration to allow
using the BNC/AUI port.
Report the TP link state only if the TP port is selected. When the
port autoselection is enabled or AUI port is selected, report the link
as always up.

The ldmvsw driver is specifically for supporting the ldom virtual
networking by running in the primary ldom and using the LDC to connect
the remaining ldoms to the outside world via a bridge. With TSO and GSO
supported while connected the bridge, things tend to misbehave as seen
in our case by delayed packets, enough to begin triggering retransmits
and affecting overall throughput. By turning off advertised support for
TSO and GSO we restore stable traffic flow through the bridge.
