Hi everybody,

I'm not sure if this issue is ppc-specific, so forgive me if it  
should have
been reported to the drivers/net/phy maintainer.

When using the MPC8248 FCC ethernet ports, the following messages  
are printed
by the kernel on the console when a link is down (ethernet cable  
unplugged):

Trying 100/FULL
Trying 100/HALF
Trying 100/HALF
Trying 100/HALF
...

This goes on forever, with a new message every 5 or 10 seconds. The  
message is
printed by drivers/net/phy/phy.c at line 463.

Those messages are pretty annoying. Commenting the pr_info() call  
gave me some
rest, but a proper fix is probably needed.

For the record, I'm using FCC1 and FCC2 with an LXT973 phy in bit- 
banging
mode.

There are two bugs at play, here.  One of which has been solved by a  
patch, which hasn't been accepted yet.  However, there's still a bug,  
in that the PHY layer assumes that autonegotiation will complete if  
the link is down.  I  believe you only see the message if you bring  
up the interface while the link is down.

I'm working on a fix for this.
