What were you trying to do that didn't work?
seems mode 5,6 doesn't support native XDP, but does support generic XDP.
When a command like ip link set dev em1 xdp obj [...] is used, then the kernel will attempt to load the program first as native XDP, and in case the driver does not support native XDP, it will automatically fall back to generic XDP.
But now, it can't automatically fall back to generic XDP, following command always fail:
ip link set bond0 xdp obj source/basic_xdp.o section xdp_drop RTNETLINK answers: Operation not supported
What is the impact of this issue to you?
