Subject: [PATCH bpf-next 3/3] selftests: xsk: Add tests for 8K and 9K frame sizes
Date: Sun, 19 Mar 2023 20:56:56 +0100	[thread overview]
Message-ID: <20230319195656.326701-4-kal.conley@dectris.com> (raw)
In-Reply-To: <20230319195656.326701-1-kal.conley@dectris.com>

Add tests:
- RUN_TO_COMPLETION_8K_FRAME_SIZE: frame_size=8192 (aligned)
- RUN_TO_COMPLETION_9K_FRAME_SIZE: frame_size=9000 (unaligned)
