Subject: [PATCH bpf-next v4 03/10] selftests/xsk: add option to only run tests in a single mode
From: Magnus Karlsson <magnus.karlsson@...el.com>
Add an option -m on the command line that allows the user to run the
tests in a single mode instead of all of them. Valid modes are skb,
drv, and zc (zero-copy). An example:
To run test suite in drv mode only:
./test_xsk.sh -m drv
