4bee1f9ac0 net/fec: restore interrupt mask after software-reset in fec_stop()
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.

28b041139e net: preserve ifreq parameter when calling generic phy_mii_ioctl().
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.

97b72e4320 fec: use interrupt for MDIO completion indication
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.

87cad5c385 net/fec: clean suspend/resume
Commit 59d4289b83 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.

In fec open/close function, we need to use phy_connect and phy_disconnect

9555b31e8c fec: fix FEC driver packet transmission breakage
Commit f0b3fbeae1 ("FEC Buffer rework")
breaks transmission of packets where the skb data buffer is not memory
aligned according to FEC_ALIGNMENT. It incorrectly passes to
dma_sync_single() the buffer address directly from the skb, instead of
the address calculated for use (which may be the skb address or one of
the bounce buffers).

It seems there is no use converting the cpu address of the buffer to
a physical either, since dma_map_single() expects the cpu address and
will return the dma address to use in the descriptor. So remove the use
of __pa() on the buffer address as well.

This patch is against 2.6.30-rc5. This breakage is a regression over
2.6.30, which does not have this problem.
