Daniel Borkmann 97bc402db7 bpf, mlx5: fix mlx5e_create_rq taking reference on prog ... In mlx5e_create_rq(), when creating a new queue, we call bpf_prog_add() but without checking the return value. bpf_prog_add() can fail since 92117d8443 ("bpf: fix refcnt overflow"), so we really must check it. Take the reference right when we assign it to the rq from priv->xdp_prog, and just drop the reference on error path. Destruction in mlx5e_destroy_rq() looks good, though.
