Subject: [PATCH bpf-next v6 4/4] selftests: xsk: Add tests for 8K and 9K frame sizes
Date: Wed, 12 Apr 2023 18:21:14 +0200 [thread overview]
Message-ID: <20230412162114.19389-5-kal.conley@dectris.com> (raw)

Add tests:
- RUN_TO_COMPLETION_8K_FRAME_SIZE: frame_size=8192 (aligned)
- UNALIGNED_9K_FRAME_SIZE: frame_size=9000 (unaligned)
