This patch adds NAPI support for VIA velocity. The new velocity_poll
function also pairs tx/rx handling twice which improves perforamance on
some workloads (e.g., netperf UDP_STREAM) significantly (that part is
from the VIA driver).

(Partially from the upstream VIA driver). Tweaking the number of
frames-per-interrupt and timer-until-interrupt can reduce the amount of
CPU work quite a lot.

via-velocity maintains a list of its devices in order to determine
whether a netdev notification applies to one of them.  That can be
determined simply by checking the netdev_ops pointer, so the list can
be removed.

Compile-tested only.

Executive summary: the bounce buffers are in my way

- they use something like a 64 * 1500 bytes area of PCI
  consistent area
- they are not resized when the MTU changes
- they are used
  - to hand-pad undersized packets. skb_pad anyone ?
  - to linearize fragmented skbs whose fragment count
    goes beyond the 7 fragments hardware limit in order
    to claim scatter-gather support

Actually the SG code is commented out and I wonder if it
could not be implemented (ab-)using the large send feature
of the chipset since the latter should support some
multi-descriptor packet transmitting.

Per Al's suggestion, get rid of the stupid stuff:
Remove cam_type switch,
And deinline things that aren't important for speed.
And make big macro and inline.
And remove some dead/unused code.
And use const char * for chip name.

The via-velocity is using a non-standard VLAN interface configured
via module parameters (yuck).

Replace with the standard acceleration interface.
It solves a number of problems with being able to handle multiple
vlans, and dynamically reconfigure.

This is compile tested only, don't have this board.

As I promised last week, here is the first pass at removing all
unnecessary printk's that exist in network device drivers currently in
promiscuous mode.  The duplicate messages are not needed so they have
been removed.  Some of these drivers are quite old and might not need an
update, but I did them all anyway.

I am currently auditing the remaining conditional printk's and will send
out a patch for those soon.

`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration.  This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).

While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

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!
