error: structure has no member named `rate''
I want to take the functionality that I found sitting in
linux-2.6.8-rc2/net/sched/sch_netem.c for a test drive but I found
that the /sbin/tc that I have does not have the necessary knobs.
So I grabbed iproute2-2.6.X-ss040702.tar.gz and tried to build it,
but I got this:
q_netem.c: In function `netem_parse_opt'':

how to change classful netem loss probability?
Hi,
I am using netem to add loss and then adding another qdisc within netem
according to the wiki. Then i want to change the netem drop probability
without having to delete the qdisc and recreate it. I try it but I get
invalid argument:
thorium-ini hedpe # tc qdisc add dev ath0 root handle 1:0 netem drop 1%
thorium-ini hedpe # tc qdisc add dev ath0 parent 1:1 handle 10: xcp

SKB paged fragment lifecycle on receive
When I was preparing Xen''s netback driver for upstream one of the things
I removed was the zero-copy guest transmit (i.e. netback receive)
support.
In this mode guest data pages ("foreign pages") were mapped into the
backend domain (using Xen grant-table functionality) and placed into the
skb''s paged frag list (skb_shinfo(skb)->frags, I hope I am using the
