Subject: [PATCH net-next 0/4] phylink/sfp updates

Hi,

I realise that net-next probably isn't open yet, but I believe folk
will find these patches "interesting" so I'm sending them to share
them with people working on this code, rather than expecting them to
be picked up this week.

The first patch adds support for using interrupts when using a GPIO
for link status tracking, rather than polling it at one second
intervals.  This reduces the need to wakeup the CPU every second.

The second patch adds support to the MII ioctl API to read and write
Clause 45 PHY registers.  I don't know how desirable this is for
mainline, but I have used this facility extensively to investigate
the Marvell 88x3310 PHY.

There have been discussions about removing "netdev" from phylink.
The last two patches remove netdev from the sfp code, which would be
a necessary step in that direction.
