From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alice Michael Date: Tue, 2 Jul 2019 08:22:52 -0400 Subject: [Intel-wired-lan] [next PATCH S7 2/9] i40e: make visible changed vf mac on host In-Reply-To: <20190702122259.79070-1-alice.michael@intel.com> References: <20190702122259.79070-1-alice.michael@intel.com> Message-ID: <20190702122259.79070-2-alice.michael@intel.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: intel-wired-lan@osuosl.org List-ID: From: Aleksandr Loktionov This patch makes changed vm mac address visible on host via ip link show command. This problem is fixed by copying last unicast mac filter to vf->default_lan_addr.addr. Without this patch if vf mac was not set from host side and if you run ip link show $pf, on host side you'd always see a zero mac, not the real vf mac that vf assigned to itself.
