hi, I have a setup that uses ipsec/esp, and in theory, since the SPI falls in the same byte location as the tcp ports, one ought to be able to set up the rx-flow-hash etc based on the spi.
But when I try something like this: # ethtool -N eth13 rx-flow-hash esp4 sdfn Cannot change RX network flow hashing options: Invalid argument I see that is error-ing out (for me) in ixgbe_set_rss_hash_opt() for nfc->flow_type == 4 (AH_ESP_V4_FLOW). But is there a significant technical reason why this cannot follow the same logic as TCP_V4_FLOW or TCP_V6_FLOW, i.e., use "sdfn" for classification (my reading of the code in that function is that tcp v4/v6 flows do sdfn by default). Related question that motivates this, has anyone looked into whether sdfn would improve perf for esp? --Sowmini ------------------------------------------------------------------------------ _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel® Ethernet, visit http://communities.intel.com/community/wired
