Sure, and comments are welcome. For Mellanox, AFAIK, the setting is
ignored.
[Darrell] There was an earlier request that we explain the setting with a
comment in the code itself. It is selectively honoured.
Flow Director setting modes: none, signature or perfect.
Enumerator:
RTE_FDIR_MODE_NONE Disable FDIR support.
RTE_FDIR_MODE_SIGNATURE Enable FDIR signature filter mode.
RTE_FDIR_MODE_PERFECT Enable FDIR perfect filter mode.
RTE_FDIR_MODE_PERFECT_MAC_VLAN Enable FDIR filter mode - MAC VLAN.
RTE_FDIR_MODE_PERFECT_TUNNEL Enable FDIR filter mode - tunnel.
