Subject: [PATCH iproute2-next 1/2] uapi: import cfm_bridge.h
Date: Sun, 4 Oct 2026 04:13:06 +0000 [thread overview]
Message-ID: <20261004041307.2683990-2-w453y.me@gmail.com> (raw)
In-Reply-To: <20261004041307.2683990-1-w453y.me@gmail.com>
The bridge CFM netlink attributes use the MEP domain, MEP direction and
CCM interval enums from cfm_bridge.h, but the header was never imported.
The bridge cfm command in the next patch needs it. Copied as is from
net-next.
