[PATCH net-next v3 0/3] ioam6: netlink multicast event

From: Justin Iurman
Date: Thu Feb 22 2024 - 18:34:15 EST


v3:
- patchset was mistakenly superseded due to same cover title used for
iproute2-next equivalent patch -> resend (renamed)
v2:
- fix warnings

Add generic netlink multicast event support to ioam6 as another solution
to share IOAM data with user space. The other one being via IPv6 raw
sockets combined with ancillary data. This patchset focuses on the IOAM
Pre-allocated Trace (the only Option-Type currently supported), and so
on IOAM "trace" events. See an example of a consumer here [1].
