Subject: [PATCH iproute2-next v2 0/2] Support RED ECN nodrop mode
Date: Mon, 23 Mar 2020 18:12:19 +0200	[thread overview]
Message-ID: <cover.1584979543.git.petrm@mellanox.com> (raw)

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.
