4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Toshiaki Makita <makita.toshiaki@xxxxxxxxxxxxx>
[ Upstream commit 07b344f494ddda9f061b396407c96df8c46c82b5 ]
put_page() can work as a fallback for freeing xdp_frames, but the
appropriate way is to use xdp_return_frame().
Fixes: cac320c850ef ("virtio_net: convert to use generic xdp_frame and xdp_return_frame API")
