SG should have nothing to do with CSUM. They are two different features,
one is for scatter/gather IO, one is HW can checksum all the packets. If
you look at net device feature, NETIF_F_SG & NETIF_F_HW_CSUM are different
flags.
What did you get when enabling IPoIB SG? I rememerbed there was a
discussion in net-dev before.
Thanks
Shirley Ma
