[bpf-next,00/17] selftests: xsk: various simplifications

Message

Magnus Karlsson July 27, 2021, 1:17 p.m. UTC

This patch set mainly contains various simplifications to the xsk
selftests. The only exception is the introduction of packet streams
that describes what the Tx process should send and what the Rx process
should receive. If it receives anything else, the test fails. This
mechanism can be used to produce tests were all packets are not
received by the Rx thread or modified in some way. An example of this
is if an XDP program does XDP_PASS on some of the packets.

This patch set will be followed by another patch set that implements a
new structure that will facilitate adding new tests. A couple of new
tests will also be included in that patch set.

Thanks: Magnus
