Mike McCormack 8a0c9228f1 sky2: Avoid down and up during sky2_reset
Rewrite sky2_reset to work with interrupts disabled and
 avoid freeing and reallocing memory.

The old code used sky2_down and sky2_up to implement sky2_reset,
 which meant interrupts could not be disabled, and the transmit and
 receive ring buffers would be free'd and reallocated.

To avoid the interrupt handler waking the transmit queue while
 we're doing a reset, it's better to have interrupts and NAPI
 polls disabled.

Note: Modified Mike's patch to do IRQ disable in sky2_down before
 calling sky2_hw_down - Stephen

Mike McCormack 200ac492b3 sky2: Allocate initial skbs in sky2_alloc_buffers
Allocate everything in one place so there's a single point
of failure in sky2_up, and sky2_rx_start can no longer fail.

Don't leave the hardware in a partially initialized state in the
case rx ring allocation fails.

As with the old code, the rx ring still needs to be fully
allocated for sky2_up to succeed.

Change Wake On Lan code to be similar to vendor driver. The definition

setting when doing power change.

Since same code is done for both shutdown and suspend, use common

stephen hemminger 375c568844 sky2: receive checksum refactoring
Break the largish case for handling receive checksum into a separate
function, and if there is a problem use dev_XXX routines to
show which hardware is the problem.

Turn one corner case into a BUG().  This only happens if the driver
is expecting one behavior but the chip does the old behavior;
only ever saw this when bringing up a new chip type and driver
was buggy.

stephen hemminger a0db28b898 sky2: resume clocks
Change the resume path to use pci write config for a couple of reasons:
1. pci_write_config_dword() allows for more error
   checking of PCI health after resume.

2. better to toggle this register on all chip types, since that
   is what vendor driver does.

stephen hemminger 3fbd9187d0 sky2: hand receive DMA mapping failures
If receive buffer mapping failed, then it was possible to get
stuck with unmapped receive buffer in DMA ring.

This would be an extremely rare condition because the driver had just
released the map for the last receive so it should be able to get
another map again (in soft-irq).

stephen hemminger a40ccc6868 sky2: revert config space change
Obviously, this register had some other impact that is causing
the regression.  Either it is masking some other access or needs
to be reset in some path.

Either, way it is best to just revert the change for 2.6.33

Mike McCormack 2ca4231de7 sky2: Enable/disable WOL per hardware device
Y2_HW_WOL_ON/Y2_HW_WOL_OFF should be set and cleared per chip,
not per port.  On dual port cards, Y2_HW_WOL_ON should be
enabled if either sky2 port has WOL enabled.

Found while reviewing code for a WOL regression, though this is
probably not the cause of the regression.

Jarek Poplawski 9db2f1bec3 sky2: Fix oops in sky2_xmit_frame() after TX timeout
During TX timeout procedure dev could be awoken too early, e.g. by
sky2_complete_tx() called from sky2_down(). Then sky2_xmit_frame()
can run while buffers are freed causing an oops. This patch fixes it
by adding netif_device_present() test in sky2_tx_complete().
