[dpdk-dev] Broken RSS hash computation on Intel 82574L

Hi Pablo,

that is an interesting information. I read the rationale in em_ethdev.c
and I was wondering, what would have to be done to enable RSS hash
computation on that card. I can live with just one RX queue, but hashes
would help me a lot. The computer which is using those NICs is not that
powerful and every bit of offloaded computation counts...

Thanks,
Martin
