Subject: net/i40e: fix setting MAC address of VF
X-Git-Tag: spdx-start~325
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8d1e8e70ff4bff2a0135aa970552f1dcc4628e43;p=dpdk.git

net/i40e: fix setting MAC address of VF

New MAC address is copied to dev->data->mac_addrs[0] before calling
setting MAC address ops. So it will fail when deleting
dev->data->mac_addrs[0]. Deleting hw->mac.addr will fix the issue.

Fixes: 943c2d899a0c ("net/i40e: set VF MAC from VF")
