xsk: relax UMEM headroom alignment
This patch removes the 64B alignment of the UMEM headroom. There is really no reason for it, and having a headroom less than 64B should be valid. Fixes: c0c77d8fb787 ("xsk: add user memory registration support sockopt") Signed-off-by: Björn Töpel <bjorn.topel@intel.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
