Many drivers use skb->tail unnecessarily.
In these situations, the code roughly looks like:
dev = dev_alloc_skb(...);
[optional] skb_reserve(skb, ...);
... skb->tail ...
But even if the skb_reserve() happens, skb->data equals
skb->tail. So it doesn't make any sense to use anything
other than skb->data in these cases.
Another case was the s2io.c driver directly mucking with
the skb->data and skb->tail pointers. It really just wanted
to do an skb_reserve(), so that's what the code was changed
to do instead.
Another reason I'm making this change as it allows some SKB
cleanups I have planned simpler to merge. In those cleanups,
skb->head, skb->tail, and skb->end pointers are removed, and
replaced with skb->head_room and skb->tail_room integers.

Now we can change the pci core to always set this pointer, as pci drivers
should use it, not the driver core callback.

The amd8111e driver directly assigns the DMA mask to the dma_mask
member of the struct pci_dev instead of using pci_set_dma_mask(). This
makes the call to pci_dma_supported() redundant as pci_set_dma_mask()
does this check.
I do not own this device so I only compile-tested this patch.

For boards that invert the SMC91x IRQ line (maybe an FPGA inverts it),
the set_irq_type() call can't assume IRQT_RISING. These particular
boards currently use OMAP-specific calls to change the trigger type,
but the boards break when set_irq_type() stops being a NOP.

Need to handle receive and transmit packet arbiter timeouts.
Transmit arbiter timeouts happens when Gigabit sends to 100Mbit port

Cleanup messages (for debug) about PHY interrrupts, because when
user can't get driver working that is often the problem.
Use a consistent way of enabling interrupts by port.

Rewrite the code for handling the Broadcom PHY to something that
works. Remove link polling because Broadcom and Yukon don't need it.
When I wrote initial code, didn't have a genesis chipset based
board to test, so it was a non-working guess.

Remove support for the non-Broadcom genesis based boards. The code
is untested, and probably won't work as is. The newer boards are all
Yukon based, and only old Genesis board I can find uses Broadcom.

The inlines and macro's needed some cleanup's and fixes:
* change name of macro SKGEMAC_REG to SK_REG to better reflect usage
and fix comments
* ditto for SK_GEXM_REG -> SK_XMAC_REG and SKGEGMA_REG -> SK_GMA_REG
* change skge_gm_ to just gm_ since it is just a local function and long
names look ugly.
* change skge_xm_ to just xm_
* fix xm_write32 to write as two u16's with correct byte order
* fix xm_outaddr to correctly use offset

Check the link state during b44_open. This closes a 1 HZ window
that existed after b44_open ran but before the b44_timer handler ran,
during which ethtool would report "Link detected: yes" no matter what
the link state actually was.
