Subject: [Intel-wired-lan] [PATCH 2/2] ixgbevf: fix MAC address changes through ixgbevf_set_mac()
Date: Mon, 14 May 2018 11:16:16 -0700 [thread overview]
Message-ID: <20180514181616.26797.73490.stgit@localhost6.localdomain6> (raw)
In-Reply-To: <20180514181449.26797.30080.stgit@localhost6.localdomain6>
Set hw->mac.perm_addr in ixgbevf_set_mac() in order to avoid losing the
custom MAC on reset. This can happen in the following case:
>ip link set $vf address $mac
>ethtool -r $vf
