Linux Ethernet Bridging - Apr 2007 - [Bridge] setportprio problem with bridge-utils 1.0.6

Thanks Stepen, again, and sorry for my english, perhaps is this the 
problem too: my english.

I want to set port prio, to values as 1, 2, 3, 4, etc.. (little values), 
my problem is that when I run:

brctl setportprio br0 eth1 3

That "3" goes to "port cost" no goes into "port
priority", that is my
problem.

Any help more?

I'm having a problem with brctl when I want to set prio in a bridge port.

When I execute:

brctl setbridgeprio br0 eth1 10

(for example)

I can see how that value (10) is asigned to the port cost.

Is this a known issue with this version?

I detected this with FC5 bridge-utils package and with dd-wrt bridge-utils.

Any help about this?

All it ends up doing is writing a 10 to /sys/class/net/br0/bridge/port_cost

The problem (or feature) is that the bridge will autodetect
the port cost based on the link speed when the bridge or port
is started up. So you need to change the port cost after the
bridge is already running to cause any effect.
