Subject: still battling with qfq
Even after yesterday's patch, I can get qfq to lock up on the
e1000e or ag71xx in under half an hour. I have not managed to
make it lock up on wireless as of yet. Same boxes runs the
new SFQ all day long.
Three changes from previous behavior - no kernel panics, and where
before doing a tc qdisc del dev eth0 root would sometimes clear it,
on the e1000e I have to plug/unplug, but on the ag71xx I can
do the tc del and have the interface come back to life.
both tx and rx lock up.
I thought maybe I was running out of bins so I tried
a huge txqueuelen on the first try... (514*24)
I'm digging up another wired card, will try again in the morning.
some logs from 5 test runs, using 50 iperfs and ping to
generate the load, on the e1000e:
