rtl8169_hw_start() requires that the descriptor ring indexes be
set to zero. Let a deferred invocation of rtl8169_reset_task()
handle it. Enabling a few power management bits will not hurt
either.

suspend/resume is issued with irq on: the spinlock do not need
to save the irq flag.

The MII registers read/write function blindly busy waits for an
amount of 1000 us (1 ms), then up to 200 ms. These functions are
called from irq disabled context. Depending on the clock management,
it triggers lost ticks events. Since the value is way above the
standard delay required for mii register access, it strangely looks
like a bandaid against posted writes.

The capabilities of the 8169 can be disabled but it is hardly a reason
to prevent the use the device. The (so far) unusual behavior has been
reported on a MIPS platform by Yoichi Yuasa.

As an alternative, people can use the boot time 'debug' option and/or use
'ethtool -s ethX msglvl xyz'.  The different messages are listed at:

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.

- removal of a few PFX used in contexts where dev->name is available;
- s/->slot_name/pci_name/;
- printed_version is redundant with the debug option. Remove it and let

  The size of the incoming frame is not correctly checked.
  
  The RxMaxSize register (0xDA) does not work as expected and incoming
  frames whose size exceeds the MTU actually end spanning multiple
  descriptors. The first Rx descriptor contains the size of the whole
  frame (or some garbage in its place). The driver does not expect
  something above the space allocated to the current skb and crashes
  loudly when it issues a skb_put.
  
  The fix contains two parts:
  - disable hardware Rx size filtering: so far it only proved to be able
    to trigger some new fancy errors;
  - drop multi-descriptors frame: as the driver allocates MTU sized Rx
    buffers, it provides an adequate filtering.
  
  As a bonus, wrong descriptors were not returned to the asic after their
  processing.

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!
