Hi Roland, I see the under connected mode the ipoib driver does not advertise S/G (NETIF_F_SG) support at its features bitmap. I understand that this would force the stack to do a copy in case the packet to be sent is made of page/fragments held at the SKB, etc.
Doesn't it make sense to support S/G also for connected mode? I know that for CSUM support, if S/G is not supported, then the stack ignores the NETIF_F_IP_CSUM bit even if its being set by the nic, but does it apply also the other way - that is if CSUM is not supported then the stack ignores NETIF_F_SG? if yes, why? Or. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
