Re: [Bug 1677297] RE: Zesty use qcom_emac instead of msm_emac.

2017-03-29 Thread Timur Tabi 
Sorry, I'm not sure what happened there.  I meant to say that that is the
*actual* PHY on the SDP board.  It's an Atheros 8031 PHY.  I was hoping
that we could get away with the genphy driver that's built-in, but
apparently not.  

Ubuntu should be building every PHY driver anyway.  I don't know if
there's a way to automatically load only the PHY drivers that are on the
board.  However, none of this is Centriq- or even ARM-specific.  This is
standard procedure for most Ethernet drivers on any platform.

It's not unrelated. That is the actusl phy on the SDP.

That is hard to SRU, we don't want to be adding unrelated modules to DI.

So clearly as a side effect of loading at803x qcom_emac is able to get an
IP address. But I am afraid this is not something we can justify as an
SRU.
