All drivers implement ethtool get_perm_addr the same way -- by calling
the generic function. So we can inline the generic function into the
caller and avoid going through the drivers.

Doing |= 1 << 19 to 16bit unsigned is not particulary useful;
that register is 32bit, unlike the ones dealt with in the rest of
function, so we need u32 variable here.

If packet larger than MTU is received, the driver uses hardware to
truncate the packet. Use the status registers to catch/drop them.

Simplify receive buffer refill logic. Rather than trying to update
incrementally; do receive ring refill at end of receive processing.

This patch avoids generating another IRQ if more packets
arrive while in the NAPI poll routine. Before marking device as
finished, it rechecks that the status ring is empty.

This patch restores a couple of workarounds from 2.6.16:
* restart transmit moderation timer in case it expires during IRQ routine
* default to having 10 HZ watchdog timer.
At this point it more important not to hang than to worry about the
power cost.

Enable support for Yukon EX chipset (88e8071).
Most of changes are related to new commands to chip for transmit,
and change in status and checksumming.

Fix sky2 disabling VLAN completely when the first vid is unregistered.
sky2 disables VLAN completely when the first VID is unregistered. It
should instead disable VLAN when the group is unregistered by calling
sky2_vlan_rx_register with grp = NULL.

This code inherited from the sk98lin driver is incorrect on the Yukon2.
The GPHY_CTRL register values are specific to the internal PHY of the chip
and the values used were leftovers.
Driver was setting bit 13 which is now the INT polarity for the PHY!

Don't need read after update to index, mmiowb() followed by read at end
of irq is sufficient.
