Subject: [PATCH v3] drivers/net/usb/asix: resync from vendor's copy
(resubmitting because I goofed on v2 of this patch -- please skip that one)
Third pass (for review) at updating the in-kernel asix usb/network driver
from the v4.1.0 vendor GPL version of the driver, obtained from here:
http://www.asix.com.tw/download.php?sub=searchresult&PItemID=84&download=driver
The original vendor copy used a local "axusbnet" middleware (rather than "usbnet").
I've converted it back to using "usbnet", made a ton of cosmetic changes
to get it to pass checkpatch.pl, and removed a small amount of code duplication.
The tx/rx checksum code has been updated per Ben's comments,
and the duplicated MII_* definitions have been removed.
I've changed the version string to be "4.1.0-kernel",
to reflect the vendor's code version while also distinguishing
this port from the original vendor code.
It can use more work going forward, but it is important to get it upstream
sooner than later -- the current in-kernel driver fails with many devices,
both old and new. This updated version works with everything I have available
to test with, and also handles suspend / resume (unlike the in-kernel one).
Signed-off-by: Mark Lord <mlord@...ox.com>
---
Note that the vendor now has a v4.2.0 version available,
but for now I'm concentrating on the original v4.1.0 code.
After review/discussion of this patch, I will update for Linux-3.2-rc
and resubmit for inclusion in the eventual linux-3.3 kernel.
Patch included below, and also attached to bypass mailer mangling.
