[dpdk-dev] [PATCH v4 14/34] net/bnxt: fetch vnic info from DPDK port

[Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>]

VNIC is needed for the driver to program the action record for rx
flows. VNIC determines what receive rings to use to place the received
packets. This patch introduces a routine that will convert a given
dpdk port to VNIC.
