Haiyang Zhang 4823eb2f3a hv_netvsc: Add ethtool handler to set and get UDP hash levels ... The patch add the functions to switch UDP hash level between L3 and L4 by ethtool command. UDP over IPv4 and v6 can be set differently. The default hash level is L4. We currently only allow switching TX hash level from within the guests. On Azure, fragmented UDP packets have high loss rate with L4 hashing. Using L3 hashing is recommended in this case. For example, for UDP over IPv4 on eth0: To include UDP port numbers in hasing: ethtool -N eth0 rx-flow-hash udp4 sdfn To exclude UDP port numbers in hasing: ethtool -N eth0 rx-flow-hash udp4 sd To show UDP hash level: ethtool -n eth0 rx-flow-hash udp4 Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: David S.
