[PATCH net-next v2 0/3] multicast event support for ioam6

From: Justin Iurman
Date: Thu Feb 22 2024 - 08:42:54 EST


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].
