To PMD maintainers: please comment if you know devices that
support tagging matching packets with more than 32 bits of
user-provided data!

[Sugesh] I guess the flow director ID is 64 bit , The XL710 datasheet says so.
And in the 'rte_mbuf' structure the 64 bit FDIR-ID is shared with
rss hash. This can be a software driver limitation that expose only
32 bit. Possibly because of cache alignment issues? Since the
hardware can support 64 bit, I feel it make sense to support 64 bit as well.

XL710 supports 32bit FDIR ID only, I believe you mix it up with flexible payload data which can take 0, 4 or 8 bytes of the RX descriptor.

Regards,
Andrey
