While there... is somebody interested in making the whole PHY lib
operate a task level and use mutexes instead of spinlock ? I need that
for drivers like EMAC (who use their own PHY layer for now), and I might
even give a go at adapting phylib myself, but I'd like to take the
temperature about it first.

Basically, there is nothing in phylib that is performance critical or
such that requires it to run at irq time and/or use locks. On the other
hand, it complicates things in various areas. The most obvious one being
that it prevents the network driver mii access callbacks from sleeping
which can be annoying as MDIO can be slow, and some drivers have fancy
muxes in there that are better off mutexed than spinlocked.

Ben.
