[dpdk-dev] [PATCH 08/10] net/bnxt: consider vlan fields for the template match criteria

[Somnath Kotur]

From: Kishore Padmanabha <kishore.padmanabha at broadcom.com>

The vlan mask fields were not setting the field bitmap causing
the template match process to ignore vlan fields. This change fixes
this bug.
