From: Tariq Toukan <tar...@mellanox.com>
Add missing description of counters.
Split tx_tls_encrypted counter into two, to give packets
and bytes indications.
Fixes: f42c104f2ec9 ("Documentation: add TLS offload documentation")

Following minimum set of TLS-related statistics should be reported
by the driver:
- * ``rx_tls_decrypted`` - number of successfully decrypted TLS segments
- * ``tx_tls_encrypted`` - number of in-order TLS segments passed to device
- for encryption
+ * ``rx_tls_decrypted_packets`` - number of successfully decrypted RX packets
+ which were part of a TLS stream.
+ * ``rx_tls_decrypted_bytes`` - number of TLS payload bytes in RX packets
+ which were successfully decrypted.
+ * ``tx_tls_encrypted_packets`` - number of TX packets passed to the device
+ for encryption of their TLS payload.
+ * ``tx_tls_encrypted_bytes`` - number of TLS payload bytes in TX packets
+ passed to the device for encryption.
+ * ``tx_tls_ctx`` - number of TLS TX HW offload contexts added to device for
+ encryption.
* ``tx_tls_ooo`` - number of TX packets which were part of a TLS stream
- but did not arrive in the expected order
- * ``tx_tls_drop_no_sync_data`` - number of TX packets dropped because
- they arrived out of order and associated record could not be found
+ but did not arrive in the expected order.
+ * ``tx_tls_drop_no_sync_data`` - number of TX packets which were part of
+ a TLS stream dropped, because they arrived out of order and associated
+ record could not be found.
+ * ``tx_tls_drop_bypass_req`` - number of TX packets which were part of a TLS
+ stream dropped, because they contain both data that has been encrypted by
+ software and data that expects hardware crypto offload.
