From a15fd8c005e75022140b5d83d15f0b10100b94f2 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Thu, 28 Jun 2018 13:15:27 -0700 Subject: [PATCH] net/bnxt: fix clear port stats PORT_CLR_STATS is not allowed for VFs, NPAR, MultiHost functions or when SR-IOV is enabled. Don't send the HWRM command in such cases.
