Merge branch 'eth-fbnic-add-network-driver-for-meta-platforms-host-network-interface' 

Alexander Duyck says:

====================
eth: fbnic: Add network driver for Meta Platforms Host Network Interface

This patch set includes the necessary patches to enable basic Tx and Rx
over the Meta Platforms Host Network Interface. To do this we introduce a
new driver and driver directories in the form of
"drivers/net/ethernet/meta/fbnic".

The NIC itself is fairly simplistic. As far as speeds we support 25Gb,
50Gb, and 100Gb and we are mostly focused on speeds and feeds. As far as
future patch sets we will be supporting the basic Rx/Tx offloads such as
header/payload data split, TSO, checksum, and timestamp offloads. We have
access to the MAC and PCS from the NIC, however the PHY and QSFP are hidden
behind a FW layer as it is shared between 4 slices and the BMC.

Due to submission limits the general plan to submit a minimal driver for
now almost equivalent to a UEFI driver in functionality, and then follow up
over the coming months enabling additional offloads and enabling more
features for the device.
