Subject: [xdp-hints] [PATCH bpf-next v5 14/21] selftests/bpf: Allow VLAN packets in xdp_hw_metadata
Date: Fri, 11 Aug 2023 18:15:02 +0200 [thread overview]
Message-ID: <20230811161509.19722-15-larysa.zaremba@intel.com> (raw)
In-Reply-To: <20230811161509.19722-1-larysa.zaremba@intel.com>
Make VLAN c-tag and s-tag XDP hint testing more convenient
by not skipping VLAN-ed packets.
Allow both 802.1ad and 802.1Q headers.
