Subject: rt2x00: Allow rt61 to catch up after a missing tx report

Sometimes it happens in the tx path that an entry given to the hardware isn't
reported in the txdone handler. This ultimately led to the dreaded "non-free
entry in the non-full queue" message and the stopping of the tx queue. Work
around this issue by allowing the driver to also clear out previos entries in
the txdone handler.

Subject: netxen: optimize tx handling

netxen driver allows limited number of threads simultaneously posting
skb's in tx ring. If transmit slot is unavailable, driver calls
schedule() or loops in xmit_frame().

This patch returns TX_BUSY and lets the stack reschedule the packet if
transmit slot is unavailable. Also removes unnecessary check for tx
timeout in the driver itself, the network stack does that anyway.

Subject: netxen: fix byte-swapping in tx and rx

Here's the reworked patch.

This cleans up some unnecessary byte-swapping while setting up tx and
interpreting rx desc. The 64 bit rx status data should be converted
to host endian format only once and the macros just need to extract
bitfields.

This saves a spate of interrupts on pseries blades caused by buggy
(non) processing rx status ring.

Subject: 3c509: PnP resource management fix

In order to release PnP resources a card type must be set to EL3_PNP.
Previously, it was never set hence the PnP resources were not
released and device was left in incorrect state.

Subject: sky2: large memory workaround.

This patch might fix problems with 4G or more of memory.
It stops the driver from doing a small optimization for Tx and Rx,
and instead always sets the high-page on tx/rx descriptors.

Subject: sky2: remove check for PCI wakeup setting from BIOS

The driver checks status of PCI power management to mark
default setting of Wake On Lan. On some systems this works, but often
it reports a that WOL is disabled when it isn't.

This patch gets rid of that check and just reports the wake on
lan status based on the hardware capablity.
