Hello,
I recently started working with udp-gro (sendmmsg extension). It seems to work great when
sending to/from intel ax210 wifi station, but when I try on mtk7922 radio, I get -EIO from
the sendmmsg call and the data packets are not seen on the network device if I sniff.
Looks like most offloads are not enabled on this netdev. Should I still expect udp-gro
sends to work (like with software fallback somewhere in the stack), or must I just not
use that feature on network cards not supporting it?
[root@ct523c-3b7f ~]# ethtool -k wlan20|grep ": on"
rx-checksumming: on [fixed]
generic-receive-offload: on
netns-local: on [fixed]
[root@ct523c-3b7f ~]# ethtool -k wlan20|grep udp
tx-udp_tnl-segmentation: off [fixed]
tx-udp_tnl-csum-segmentation: off [fixed]
tx-udp-segmentation: off [fixed]
rx-udp_tunnel-port-offload: off [fixed]
rx-udp-gro-forwarding: off
Thanks,
Ben
