xsk: do not return ENXIO from TX copy mode
This patch removes the ENXIO return code from TX copy-mode when someone has forcefully changed the number of queues on the device so that the queue bound to the socket is no longer available. Just silently stop sending anything as in zero-copy mode so the error reporting gets consistent between the two modes. Fixes: 35fcde7f8deb ("xsk: support for Tx") Signed-off-by: Magnus Karlsson <magnus.karlsson@intel.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
