[-- Attachment #1: Type: text/plain, Size: 493 bytes --]

New set of patches, following Jeff comments on my previous posts.
Patches are tested and are against latest netdev-2.6 tree

After applying all these patches you get:
- sis900 debug output filtered with netif_msg macros
- ethtool support for changing debug output
- Correct printk() logging level
- simplification of chip revision code

As usual they are available also from:
http://teg.homeunix.org/sis900.html

Infrastructure needed for standard netif messages
 - add msg_level to sis900_private
 - define default msg level
 - set default value for sis900_debug
Update module parameter description
Ethtool support for debugging output level

Chip revision is now a member of sis_priv structure
Kill all calls to pci_read_config_byte but one
Change the code to use sis_priv->chipset_rev

Patches 1, 2, and 5 are OK.

For the other two patches, I don't want to deviate from the style that 
has been standard for years:  dev->name prefix, followed by message.

It may make greps easier for you, but it becomes a non-standard style 
and may make existing sysadmin scripts out in the field.

Please resend series without the PFX-where-devname-is-known changes.

	Jeff

Ok, I just don't have time to do it right now, but I'll rediff ASAP.
However a message reformat patch will be needed because there are some
messages that don't conform to either (mine or established) standard.

Also I think I'll add at the end of the patchset a new patch that was
sent recently on linux-kernel that adds support for netconsole.


Bye.
