[PATCH] via-velocity: Add missing KERN_<LEVEL> where needed

[PATCH] via-velocity: Add missing KERN_<LEVEL> where needed

[Joe Perches]

Link status is emitted on multiple lines as it does not use
KERN_CONT.

Coalesce the multi-part logging into a single line output and
add missing KERN_<LEVEL> to a couple logging calls.

This also reduces object size.

The real problem is the whole VELOCITY_PRT() private debug log
control business this driver is doing.

It should be using the standard netdev logging level infrastructure.

You can't tell me that this "KERN_INFO blah blah blah" is really
something we should add more of these days, right?

If you're going to improve this driver's logging code please do
so by having it use the standard interfaces.

Thanks.

The existing code is not great and definitely odd.

This is just a bug fix until such time as it's better.

VELOCITY_PRT is not just used for debugging.

The default is output if MSG_LEVEL_INFO and
there's a control for further output.

This is just fixing Linus' change for KERN_CONT
uses on separate lines from awhile ago.

It'd be nice if a via maintainer actually fixed it.

[PATCH V2] via-velocity: Use more typical logging styles

[Joe Perches]

Use netdev_<level> in place of VELOCITY_PRT.
Use pr_<level> in place of printk(KERN_<LEVEL>.

Miscellanea:

o Add pr_fmt to prefix pr_<level> output with "via-velocity: "
o Remove now unused functions and macros
o Realign some logging lines
o Remove devname where pr_<level> is also used
