Nikhil P. Rao 3f2793713c xsk: Fix zero-copy AF_XDP fragment drop ...

[ Upstream commit f7387d6579 ]

AF_XDP should ensure that only a complete packet is sent to application.
In the zero-copy case, if the Rx queue gets full as fragments are being
enqueued, the remaining fragments are dropped.

For the multi-buffer case, add a check to ensure that the Rx queue has
enough space for all fragments of a packet before starting to enqueue
them.
