689be43945 [NET]: Remove gratuitous use of skb->tail in network drivers.
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.

0e396ee43e Manual merge of rsync://rsync.kernel.org/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git
This is a fixed-up version of the broken "upstream-2.6.13" branch, where
I re-did the manual merge of drivers/net/r8169.c by hand, and made sure
the history is all good.

b57b7e5a11 [PATCH] r8169: ethtool message level control support
Also:
- ratelimit the too much work at interrupt message, so if under massive
  packet load the console doesn't get flooded;
- 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 user decide.

f7ccf420e5 [PATCH] r8169: identify the napi version
To tell if driver is configured for NAPI or not, put -NAPI on driver
version. Remove the NAPI printk since the complete version information
is displayed once in the pci probe routine or returned via ethtool.

a7b6459de1 [PATCH] r8169: new PCI id
The USR 997902 is based on the 8169 chipset.

The value has been extracted from the sources of the driver which
comes with the manufacturer's cdrom. Heads-up and test by TommyDrum

126fa4b9ca [PATCH] r8169: incoming frame length check
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.

1da177e4c3 Linux-2.6.12-rc2
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!
