Series multicast event support for ioam6 |

Commit Message

Justin Iurman Feb. 22, 2024, 1:42 p.m. UTC 
  Add new api to support ioam6 events for generic netlink multicast. A
first "trace" event is added to the list of ioam6 events, which will
represent an IOAM Pre-allocated (or Incremental) Trace Option-Type. It
provides another solution to share IOAM data with user space.
