[PATCH bpf 0/2] Fix some corner cases in xskxceiver

Posted by Larysa Zaremba 4 days, 17 hours ago

While working on XDP and AF_XDP support for ixgbevf driver,
I came across two distinct problems that caused tests to fail
when they shouldn't have.

Larysa Zaremba (2):
  selftests/xsk: properly handle batch ending in the middle of a packet
  selftests/xsk: fix number of Tx frags in invalid packet
