Subject: [PATCH bpf-next v3 04/10] selftests/xsk: move all tests to separate functions
From: Magnus Karlsson <magnus.karlsson@...el.com>
Prepare for the capability to be able to run a single test by moving
all the tests to their own functions. This function can then be called
to execute that test in the next commit.
Also, the tests named RUN_TO_COMPLETION_* were not named well, so
change them to SEND_RECEIVE_* as it is just a basic send and receive
test of 4K packets.
