Merge branch 'eth-fbnic-fix-and-improve-header-data-split-configuration'

Bobby Eshleman says:

====================
eth: fbnic: fix and improve header/data split configuration

This series fixes TCP HDS configuration in the fbnic driver and adds a
devmem selftest for the intended behavior.

The issues fixed include setting the correct CSR for EN_HDR_SPLIT,
adjusting the hds threshold clamp to avoid long headers overflowing into
the payload page, and configuring the device to use L4/L3/L2 header
boundaries when present by programming the DMA hint bit unconditionally
for all steering rule types.

Prior to these fixes, small payloads fail devmem.check_rx_hds().

Testing:

IFC0=enp1s0
IFC1=eth0

export REMOTE_TYPE=netns
export REMOTE_ARGS=ns-remote
export NETIF=$IFC0
export LOCAL_V4=192.0.3.1
export REMOTE_V4=192.0.3.2
sysctl -w net.ipv6.conf.$IFC0.keep_addr_on_down=1

./tools/testing/selftests/drivers/net/hw/devmem.py

TAP version 13
1..4
ok 1 devmem.check_rx
ok 2 devmem.check_tx
ok 3 devmem.check_tx_chunks
ok 4 devmem.check_rx_hds
