but did not arrive in the expected order.
* ``tx_tls_skip_no_sync_data`` - number of TX packets which were part of
a TLS stream and arrived out-of-order, but skipped the HW offload routine
and went to the regular transmit flow as they were retransmissions of the
connection handshake.

a TLS stream dropped, because they arrived out of order and associated
