Subject: [PATCH net-next 00/10] bpf: xdp: Report bpf_prog ID in IFLA_XDP

This is the first usage of the new bpf_prog ID.  It is for
reporting the ID of a xdp_prog through netlink.

It rides on the existing IFLA_XDP.  This patch adds IFLA_XDP_PROG_ID
for the bpf_prog ID reporting.

It starts with changing the generic_xdp first.  After that,
the hardware driver is changed one by one.  The final patch
removes the prog_attached from 'struct netdev_xdp' because
prog_id > 0 implies the presence of xdp_prog.

I have tested with generic_xdp, mlx4 and mlx5.

Martin KaFai Lau (10):
