net/cxgbe: support flow API for matching all packets on VF

Add support to match all packets received on the underlying VF.

Use new firmware API to fetch the Virtual Interface Number (VIN)
allocated to each VF by the firmware. The VIN is required to
write filter rules to match all packets on VFs, whose identifier
is beyond max 7-bit value (i.e. 127) in VIID.

If firmware doesn't support fetching the VIN information, then
fallback to manually retrieving the VIN value from the 7-bit field
in the VIID, which only supports in range of 0..127. In this case,
packets belonging to VFs, whose identifier is beyond 127 can't be
matched.
