Further refactor XDP attachment code. dev_change_xdp_fd() is split into
two
parts: getting bpf_progs from FDs and attachment logic, working with
bpf_progs. This makes attachment logic a bit more straightforward and
prepares code for bpf_xdp_link inclusion, which will share the common
logic.
It looks like this patch breaks xdp tests for me:
* test_xdping.sh
* test_xdp_vlan.sh
Can you please verify on your side?
Looking at tools/testing/selftests/bpf/xdping.c I see it has:
static __u32 xdp_flags = XDP_FLAGS_UPDATE_IF_NOEXIST;
And it attaches program two times in the same net namespace,
so I don't see how it could've worked before the change :-/
(unless, of coarse, the previous code was buggy).
