Subject: [PATCH net-next v2 5/5] bpf: update XDP selftests to not fail with generic XDP
Date: Wed, 23 Jun 2021 01:25:27 +0530	[thread overview]
Message-ID: <20210622195527.1110497-6-memxor@gmail.com> (raw)
In-Reply-To: <20210622195527.1110497-1-memxor@gmail.com>

Generic XDP devmaps and cpumaps now allow setting value_size to 8 bytes
(so that prog_fd can be specified) and XDP progs using them succeed in
SKB mode now. Adjust the checks.
