Subject: [BUG,BISECTED] mvneta: second interface no more usable on mirabox
Date: Tue, 16 Jun 2015 23:44:00 +0200 [thread overview]
Message-ID: <87a8vz72hr.fsf@natisbad.org> (raw)
Hi,
On Mirabox, the second ethernet interface is no more usable on 4.1-rc*
series (no packets coming out of the interface, when using dhclient for
instance). It works as expected on 4.0.
Bisecting the issue, I ended up on 898b2970e2c9 ("mvneta: implement
SGMII-based in-band link state signaling"). Reverting that commit gives
me back the second interface.
Then, I also tested on a NETGEAR ReadyNAS 104, which is also powered by
the same SoC (Armada 370) and also has two (mvneta-supported) ethernet
interfaces. With an unmodified 4.1-rc8, only one of the two interfaces
is available. Reverting 898b2970e2c9 makes both usable again.
FWIW, mirabox and RN104 ethernet interfaces use RGMII.
Cheers,
a+
