Subject: [PATCH bpf-next 04/10] selftests/xsk: move all tests to separate functions
Date: Wed, 9 Aug 2023 14:43:37 +0200 [thread overview]
Message-ID: <20230809124343.12957-5-magnus.karlsson@gmail.com> (raw)
In-Reply-To: <20230809124343.12957-1-magnus.karlsson@gmail.com>
From: Magnus Karlsson <magnus.karlsson@intel.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.
