Thanks, Squashed this change as

    doc: fix eventdev doc updates

    Fixed release notes for changes made in eventdev library.
    Also updated the eventdev guide had got the type of the
    rte_event_vector struct's u64s union field wrong.

    Fixes: 5fa63911e43b ("eventdev: replace padding type in event vector")
    Fixes: 0fbb55efa542 ("eventdev: add element offset to event vector")
    Fixes: d986276f9b72 ("eventdev: add prefix to public symbol")
    Fixes: 1cc44d409271 ("eventdev: introduce event vector capability")
