- for messages identification I use header's field called 'msg_cnt'.
  May be it is better to call it 'msg_id' or 'msg_num', because it
  is used as ID, but implemented as counter.

- in current version of specification, some values of headers' fields
  still unnamed, for example type of socket (stream or seqpacket), then
  shutdown flags. Spec says that for stream socket value of 'type'
  must be 1. For receive shutdown bit 0 is set in 'flags', for send
  shutdown bit 1 is set in 'flags'. But in Linux these unnamed ones and
  zeroes are implemented as enums, so may be it will be ok to add such
  enums in specification (as 'enum virtio_vsock_event_id').
