Subject: [PATCH bpf-next v2 02/10] selftests: xsk: Use correct UMEM size in testapp_invalid_desc
Date: Wed, 29 Mar 2023 20:04:54 +0200	[thread overview]
Message-ID: <20230329180502.1884307-3-kal.conley@dectris.com> (raw)
In-Reply-To: <20230329180502.1884307-1-kal.conley@dectris.com>

Avoid UMEM_SIZE macro in testapp_invalid_desc which is incorrect when
the frame size is not XSK_UMEM__DEFAULT_FRAME_SIZE. Also remove the
macro since it's no longer being used.

Fixes: 909f0e28207c ("selftests: xsk: Add tests for 2K frame size")
Signed-off-by: Kal Conley <kal.conley@dectris.com>
