Re: [CFT 4/8] net: axienet: use resolved link config in mac_link_up()

[Russell King - ARM Linux admin <linux@armlinux.org.uk>]

Hi Andre,

Are you able to give this (along with patch 1) some testing please?
The series can be grabbed from:

  https://patchwork.ozlabs.org/series/159037/mbox/

Strangely, google doesn't find it in the lore.kernel.org archives,
but does in spinics.net archives and patchwork...
