> 
> The patch [Fixes] sets the default value of required minimal inline data to 0
> bytes. On some configurations (depends on switchdev/legacy settings and
> FW version/settings) the ConnectX-4LX NIC requires minimal 18 bytes of Tx
> descriptor inline data to operate correctly.
> 
> Wrongly set to 0 default value may prevent NIC from operating with out-of-
> the-box settings, this patch reverts default value for ConnectX-4LX back to 18
> bytes (inline L2).
