The kernel supports a new RED mode, "ECN nodrop". In the nodrop mode,
non-ECT packets are always queued, instead of being subject to early
dropping.

This patchset adds support for the RED ECN nodrop mode to iproute2. In
patch #1, kernel headers are synced. #2 adds support for the new mode and
describes it in the man page.

v2:
- Patch #2:
    - When dumping, read TCA_RED_FLAGS as nla_bitfield32 instead of u32.

Petr Machata (2):
  uapi: pkt_sched: Update headers for RED nodrop
  tc: q_red: Support 'nodrop' flag
