Subject: [xdp-hints] [PATCH bpf-next v4 11/21] ice: use VLAN proto from ring packet context in skb path
Date: Fri, 28 Jul 2023 19:39:13 +0200 [thread overview]
Message-ID: <20230728173923.1318596-12-larysa.zaremba@intel.com> (raw)
In-Reply-To: <20230728173923.1318596-1-larysa.zaremba@intel.com>
VLAN proto, used in ice XDP hints implementation is stored in ring packet
context. Utilize this value in skb VLAN processing too instead of checking
netdev features.
At the same time, use vlan_tci instead of vlan_tag in touched code,
because vlan_tag is misleading.
