Re: remus error

[Ashish Bijlani <ashish.bijlani@gmail.com>]

Yes I was successfully able to run " tc qdisc add dev vif3.0 root queue"

"tc qdisc show" prints this:

qdisc pfifo_fast 0: dev peth0 root bands 3 priomap  1 2 2 2 1 2 0 0 1
1 1 1 1 1 1 1
qdisc pfifo_fast 0: dev imq0 root bands 3 priomap  1 2 2 2 1 2 0 0 1 1
1 1 1 1 1 1
qdisc queue 8001: dev vif3.0 root

all the modules are loaded

Module                  Size  Used by
sch_queue               3384  1
ebtable_filter          2696  1
ebtables               16008  1 ebtable_filter
ebt_imq                 1640  1
imq                     6192  0
xt_IMQ                  2056  0

I think I may have made a mistake while porting rtnetlink to new
netlink API. I'm looking at that. Hopefully should be able to fix
that. I'll update soon.

Thanks,
Ashish
