This patch series deals with a removing a IP feature that can be found
on all currently supported Marvell Ethernet IP (pxa168_eth, mv643xx_eth,
mvneta). The MAC IP allows to automatically perform PHY auto-negotiation
without software interaction.
However, this feature (a) fundamentally clashes with the way libphy works
and (b) is unable to deal with quirky PHYs that require special treatment.
In this series, pxa168_eth driver is rewritten to completely disable that
feature and properly deal with libphy provided PHYs. The other two drivers
are suspect to future patch sets, also removing the code related with it.
Hum, in mvneta, we already disabled the automatic negotiation and use
libphy. What makes you think the current mvneta driver is wrong in this
respect?
I didn't check mvneta, but remember Ezequiel didn't clear all AN bits
in the barebox driver (which is based on Linux mvneta). Just mentioned
that I'll have a closer look at it.
But I agree, regarding libphy support mvneta is probably the best
already.
