[dpdk-dev] [PATCH v2 13/20] net/bnxt: check for invalid VNIC ID in vnic tpa cfg

[Ajit Khaparde]

From: Somnath Kotur <somnath.kotur at broadcom.com>

If driver init/probe fails as part of cleanup/rollback, we may end
up invoking this HWRM cmd even on an invalid vNIC which will unecessarily
log an error message as the cmd will fail.
Check for invalid ID before issuing the HWRM cmd
