Bleep bloop. Greetings Yi-Hung Wei, I am a robot and I have tried out your
patch.
Thanks for your contribution.
I encountered some error that I wasn't expecting. See the details below.

The patch detects the numa node id from the name of the netdev,
by reading the '/sys/class/net//device/numa_node'.
If not available, ex: virtual device, or any error happens,
return numa id 0. Currently only the afxdp netdev type uses it,
other linux netdev types are disabled du

Hi Nicolas,
I was wrong. Actually with existing OVS internal device, the xdp generic mode
works fine. Please see my test on kernel 5.3 below

ip addr add dev br0 10.1.1.2/24
ip link set dev br0 up

When ofproto/trace detects a recirc action it resumes execution at the
specified next table. However, if the ct action performs SNAT/DNAT,
e.g., ct(commit,nat(src=1.1.1.1:4000),table=42), the src/dst IPs and
ports in the oftrace_recirc_node->flow field are not updated. This leads
to misleading outp
