Merge branch 'sonic-next'

Finn Thain says:

====================
Improvements for SONIC ethernet drivers

Now that the necessary sonic driver fixes have been merged, and the merge
window has closed again, I'm sending the remainder of my sonic driver
patch queue.

A couple of these patches will have to be applied in sequence to avoid
'git am' rejects. The others are independent and could have been submitted
individually. Please let me know if I should do that.

The complete sonic driver patch queue was tested on National Semiconductor
hardware (macsonic), qemu-system-m68k (macsonic) and qemu-system-mips64el
(jazzsonic).
