Make phy 0 actually be read, as it is not being right now as we have:
int mii_status = mdio_read(dev, phy, MII_BMSR);
int phyx = phy & 0x1f;
When we should have instead:
int phyx = phy & 0x1f;
int mii_status = mdio_read(dev, phyx, MII_BMSR);
so that when phy, in the end of the (phy = 1; phy <= 32...) loop gets
to 32 phyx gets to 0, i.e. we were reading at 32, when the intended
read was for 0.

Under heavy PCI bus load, ports of the DFE-580TX 4-ethernet port board stop
working, with currently no other cure than a powercycle. Here is a tested
fix. By the way, I also fixed some references and attribution.

Include MII address 0 at the end of the PHY scan. This covers the
entire range of possible MII addresses.

Expand the mask used when reseting the chip to include the GlobalReset
bit. This fix comes from ICPlus and seems to be required for some
cards.

Remove an if (1) { ... } block in sundance_probe1. Its purpose seems
to be only to allow for delaring some extra local variables. But, it also
adds ugly indentation without adding any meaning to the code.

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.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
