[PATCH 0/5] PKT_SCHED: Convert Qdiscs to use generic network statistics/estimator

[Thomas Graf <tgraf@xxxxxxx>]

Dave,

This patchset converts Qdiscs to use the generic network
statistics/estimator. A new TLV type TCA_STATS2 is introduced
carrying the new statistics while the old TLV type TCA_STATS
is still provided for backward compatibility.

Patch 1: Replace tc_stats with new gnet_stats in struct Qdisc
Patch 2: Use gnet_stats API to copy statistics into netlink message
Patch 3: Introduce gen_replace_estimator
Patch 4: Use generic rate estimator
Patch 5: Qdisc are not supposed to dump TCA_STATS themselves

I tested these patches for a few days and didn't encounter
any problems. iproute2 is able to read out statistics via
backward compatibility. A slightly patched iproute2 can
read the new statistics.
