Subject: [PATCH net-next] sfc: Add X4 PF support
From: Jonathan Cooper <jonathan.s.cooper@....com>
Add X4 series. Most functionality is the same as previous
EF10 nics but enough is different to warrant a new nic type struct
and revision; for example legacy interrupts and SRIOV are
not supported.
Most removed features will be re-added later as new implementations.
Signed-off-by: Jonathan Cooper <jonathan.s.cooper@....com>
