Subject: net/bnxt: check for invalid vNIC id
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e9950366d08f20e4d968fd76dcd0d5bc8afc09a0;p=dpdk.git

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.

Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
