Subject: Re: [PATCH] net: mvneta: properly disable HW PHY polling and ensure
 adjust_link() works

Just booted with the patch on my Mirabox.  Both interfaces work!
Thank you Thomas.

One remaining issue is that the interface which uBoot didn't configure
is still getting a random mac address:

mvneta d0070000.ethernet eth0: Using hardware mac address f0:ad:4e:01:dc:97
mvneta d0074000.ethernet eth1: Using random mac address d2:35:dd:c8:99:48

This is on 3.11 plus Thomas' patch, which includes the previous fix to
"read MAC address from hardware when available".  Perhaps that fix
isn't working with the phylib?

Thanks again,

Ethan
