Subject: [dpdk-dev] [PATCH v2 04/12] net/cxgbe: fix parsing VLAN ID rewrite action
Date: Sat, 28 Sep 2019 02:00:04 +0530 [thread overview]
Message-ID: <9408d1e3212fac76f1920501efba67ef075df02d.1569611036.git.rahul.lakkireddy@chelsio.com> (raw)
In-Reply-To: <cover.1569611036.git.rahul.lakkireddy@chelsio.com>
In-Reply-To: <cover.1569611036.git.rahul.lakkireddy@chelsio.com>
Set VLAN action mode to VLAN_REWRITE only if VLAN_INSERT has not been
set yet. Otherwise, the resulting VLAN packets will have their VLAN
header rewritten, instead of pushing a new outer VLAN header.
Also fix the VLAN ID extraction logic and endianness issues.
