Thanks for the patches. The set lgtm.
The selftest patch 11 and 17 have conflicts with the recent changes in
selftests/bpf/xsk.{h,c} and selftests/bpf/Makefile. eg. it no longer needs
XSK_LIBBPF_FLAGS__INHIBIT_PROG_LOAD, so please respin. From a quick look, it
should be some minor changes.
Not sure if Tariq has a chance to look at the mlx5 changes shortly. The set is
getting pretty long and the core part is ready with veth and mlx4 support. I
think it is better to get the ready parts landed first such that other drivers
can also start adding support for it. One option is to post the two mlx5 patches
as another patchset and they can be reviewed separately.
