v5: - remove the "must be the destination" check before sending an ioam6 event v4: - rebase on top of net merge v3: - patchset was mistakenly superseded due to same cover title used for iproute2-next equivalent patch -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 (or packet socket, if the listener does not need the processing of the IOAM Option-Type, since the hook is before in that case). This patchset focuses on the IOAM Pre-allocated Trace (the only Option-Type currently supported in the kernel), and so on IOAM "trace" events. See an example of a consumer here [1].
