[dpdk-dev] [PATCH v2 19/19] net/bnxt: check for mismatch of control and physical port

[Venkat Duvvuru]

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

During the parsing of the ingress port ignore for a flow, added
check to match the control port and the physical port that is configured
to be ignored. If they do not match then the configuration to setup the
svif ignore shall fail.
