Subject: [dpdk-dev] [PATCH 05/22] net/ice/base: add VLAN TPID for VLAN filters
Date: Tue, 3 Aug 2021 16:38:00 +0800 [thread overview]
Message-ID: <20210803083817.1243796-6-wenjun1.wu@intel.com> (raw)
In-Reply-To: <20210803083817.1243796-1-wenjun1.wu@intel.com>
From: Qi Zhang <qi.z.zhang@intel.com>
[ upstream commit a6b975d23c10756083357355372c4f545ddc1ebe ]
Currently VLAN filters via RID4 are only based on VLAN ID. However, with
incoming support for Double VLAN Mode (DVM), the driver needs to be able
to support filtering on VLAN ID + VLAN TPID (i.e. 0x8100, 0x88a8, etc.).
Add support for this by adding two fields to the ice_fltr_info
structure. First, add the tpid_valid field so the code can determine
whether or not to overwrite the default 0x8100 value for programming
packets or use the tpid field.
