[PATCH 0/2] virtio-net: close() to follow mirror of open()
Hi,
This two small patches improves ndo_close() callback to follow
the mirror sequence of ndo_open() callback. This improves the code auditing
and also ensure that xdp rxq info is not unregistered while NAPI on
RXQ is ongoing.
Please review.
Patch summary:
patch-1 ensures that xdp rq info is unregistered after rq napi is disabled
patch-2 keeps the mirror sequence for close() be mirror of open()
