veth: sctp: add NETIF_F_SCTP_CRC to device features
Commit b17c706987fa ("loopback: sctp: add NETIF_F_SCTP_CSUM to device features") added NETIF_F_SCTP_CRC to device features for lo device to improve the performance of sctp over lo. This patch is to add NETIF_F_SCTP_CRC to device features for veth to improve the performance of sctp over veth. Before this patch: ip netns exec cs_client netperf -H 10.167.12.2 -t SCTP_STREAM -- -m 10K Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 212992 212992 10240 10.00 1117.16 After this patch: ip netns exec cs_client netperf -H 10.167.12.2 -t SCTP_STREAM -- -m 10K Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 212992 212992 10240 10.20 1415.22 Tested-by: Li Shuang <tjlishuang@yeah.net> Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.
