From e9950366d08f20e4d968fd76dcd0d5bc8afc09a0 Mon Sep 17 00:00:00 2001 From: Jay Ding Date: Thu, 28 Jun 2018 13:15:38 -0700 Subject: [PATCH] net/bnxt: check for invalid vNIC id Passing an invalid fw_vnic_id to the firmware will cause the bnxt_hwrm_vnic_plcmode_cfg command to fail. Add a check for VNIC id before sending message to firmware.
