[PATCH 0/4] atl1: Attansic L1 ethernet driver

[Jay Cliburn]

This is the latest submittal of the patchset providing support for the 
Attansic L1 gigabit ethernet adapter.  This patchset is built against 
kernel version 2.6.20-rc4 current git as of 20070109.

The monolithic version of this patchset may be found at:
ftp://hogchain.net/pub/linux/m2v/attansic/kernel_driver/atl1-2.0.3/atl1-2.0.3-linux-2.6.20.rc4.patch.bz2

As a reminder, this driver is a modified version of the Attansic reference 
driver for the L1 ethernet adapter.  Attansic has granted permission for 
its inclusion in the mainline kernel.

Changes for this version include:
* Incorporation of previous comments from Arnd Bergmann, Alan Cox, and
  Jan Engelhardt.
* Conversion to the new workqueue method.
* Addition of MSI support (thanks to Luca Tettamanti).

NOTES:
1.  TSO is broken (order of magnitude decrease in Tx peformance as compared
to Rx performance) and therefore the feature has been disabled until it's
fixed.  We have not been able to find the source of the problem in the 
driver itself, so we've requested that Attansic take a look at the hardware.
We've not yet heard back from them.  We encourage any experienced netdev
folks to take a look at the TSO code and let us know if you see the problem.

2.  Given the download statistics from Sourceforge (current home of the
driver) and hogchain.net (the original home of the driver), we believe the 
driver to be in use by dozens, if not hundreds, of users.  We've received 
remarkably few bug reports:  a couple of typos and and the TSO performance 
issue.

Perhaps a dumb question, but when can I begin submitting differential 
patches?  Now?  I'd like to incorporate some of Arjan's and Randy's 
comments.

Thank you very much for accepting the driver.

OK, I have merged the monolithic patch into jgarzik/netdev-2.6.git#atl1. 
  Once I'm done merging patches tonight, I will merge this new 'atl1' 
branch into the 'ALL' meta-branch, which will auto-propagate this driver 
into Andrew Morton's -mm for testing.

For future driver updates, please send a patch rather than the full 
driver diff.

If it looks good, we will push for 2.6.21 (or 2.6.22, if updates or 
objections continue to come fast and furious).  It's in "the system" 
now, thanks for all your hard work!
