Subject: [bpf-next PATCH 2/3] bpf: make TC vlan bpf_helpers avail to selftests
Date: Tue, 25 Sep 2018 16:25:54 +0200 [thread overview]
Message-ID: <153788555479.7040.10987862426583704510.stgit@firesoul> (raw)
In-Reply-To: <153788541527.7040.8722029216689268562.stgit@firesoul>
The helper bpf_skb_vlan_push is needed by next patch, and the helper
bpf_skb_vlan_pop is added for completeness, regarding VLAN helpers.
