[PATCH v1] net: phy: fix auto-negotiation stall due to unavailable interrupt




Hello Florian, Roger and Madalin!

This is slightly modified version of previous patch[1].

It take into account that phy_start_aneg() may be called from
differend places not only from PHY state machine. So the patch
use phy_trigger_machine() to schedule link state update
correctly.

I borrow some text from Roger's commit message.

Added 'Cc: stable <stable@xxxxxxxxxxxxxxx> tag'
because the problem exist on 4.9 and 4.10 branches.

Don't know what commit brake the code, so I don't add
Fixes tag.

Roger, could you please test this one patch?

Madalin, I found, that you tested Roger’s patch[2] and this
one patch will get upstream instead of patch[2]. Could you
please test it?

Regards,
Alexander.
