net: allow FEC driver to use fixed PHY support

2010-10-13T16:56:31+00:00

At least one board using the FEC driver does not have a conventional
PHY attached to it, it is directly connected to a somewhat simple
ethernet switch (the board is the SnapGear/LITE, and the attached
4-port ethernet switch is a RealTek RTL8305). This switch does not
present the usual register interface of a PHY, it presents nothing.
So a PHY scan will find nothing - it finds ID's of 0 for each PHY
on the attached MII bus.

After the FEC driver was changed to use phylib for supporting PHYs
it no longer works on this particular board/switch setup.

Add code support to use a fixed phy if no PHY is found on the MII bus.
This is based on the way the cpmac.c driver solved this same problem.

net/fec: carrier off initially to avoid root mount failure

2010-10-11T04:12:27+00:00

with hardware slow in negotiation, the system did freeze
while trying to mount root on nfs at boot time.

the link state has not been initialised so network stack
tried to start transmission right away. this caused instant
retries, as the driver solely stated business upon link down,
rendering the system unusable.

notify carrier off initially to prevent transmission until
phylib will report link up.

net/fec: restore interrupt mask after software-reset in fec_stop()

2010-07-22T21:14:46+00:00

After the change from mdio polling to irq, it became necessary to
restore the interrupt mask after resetting the chip in fec_stop().
Otherwise, with all irqs disabled, no communication with the PHY will be
possible after e.g. un-/replugging the cable and the device gets
stalled.

net: preserve ifreq parameter when calling generic phy_mii_ioctl().

2010-07-19T02:15:25+00:00

The phy_mii_ioctl() function unnecessarily throws away the original ifreq.
We need access to the ifreq in order to support PHYs that can perform
hardware time stamping.

Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl().
This is unnecessary since phylib will check the command in any case.

fec: use interrupt for MDIO completion indication

2010-07-13T03:21:48+00:00

With the move to phylib (commit e6b043d) I was seeing sporadic "MDIO write
timeout" messages. Measure of the actual time spent showed latency times of
more than 1600us.

This patch uses the MII event indication of the FEC hardware to detect
completion of MDIO transactions.

net/fec: clean suspend/resume

2010-06-26T04:33:14+00:00

Commit 59d4289b83b11379d867e2f7146904b19cc96404 converted fec to dev_pm_ops but
didn't update the suspend/resume functions thus leading to the following warning :
"initialization from incompatible pointer type" when CONFIG_PM is set.

This patch also fixe a few indentation and style around CONFIG_PM area.
