[Cerowrt-devel] another sets of leaps forward for linux packet queueing

Eric Dumazet just posted a pure fq scheduler (using the highly optimized
red/black trees in the kernel)

http://marc.info/?l=linux-netdev&m=137740009008261&w=2

which "scales to millions of concurrent flows per qdisc".Jon Corbet wrote
it up in (subscriber only link) in lwn http://lwn.net/Articles/564978/
which also details the new tso sizing patch, which fixes the oft complained
about overlarge tso problem and does much saner things with it....

http://thread.gmane.org/gmane.linux.network/281264

Almost simultaneously Stephen Hemminger wrote a sysctl option making it
possible to easily switch the default qdisc from pfifo_fast to "something
else"

http://marc.info/?l=linux-netdev&m=137764555622344&w=2

And earlier in the week Jesper Bauer got the last of the atm/htb fixes in.

All of these patches are now in the net-next tree. There were a few
touchups and tweaks here and there over the days following, that aren't in
there yet...

Future looks so bright we gotta wear shades, or eyepatches, or something....
