Subject: [dpdk-dev] [PATCH 12/12] net/cxgbe: add rte_flow support for setting VLAN PCP
Date: Sat, 7 Sep 2019 03:22:33 +0530 [thread overview]
Message-ID: <3832fb120b0d5c9712ca41036d6a9c40547106f0.1567799552.git.rahul.lakkireddy@chelsio.com> (raw)
In-Reply-To: <cover.1567799552.git.rahul.lakkireddy@chelsio.com>
In-Reply-To: <cover.1567799552.git.rahul.lakkireddy@chelsio.com>
Add support for setting VLAN PCP field via rte_flow API. Hardware
overwrites the entire 16-bit VLAN TCI field. So, both VLAN VID and
PCP actions must be specified.
