* zero-length RESERVED TLV to pad).
|

|
|
* TLV data has two sections. First is an array of statistics' IDs (2B each).
|
||
|
|
* Second 8B statistics themselves. Statistics are 8B aligned, meaning there
|
||
|
|
* may be a padding between sections.
|
||
|
|
* Number of statistics can be determined as floor(tlv.length / (2 + 8)).
|
||
|
|
* This TLV overwrites %NFP_NET_CFG_STATS_* values (statistics in this TLV
|
||
|
|
* duplicate the old ones, so driver should be careful not to unnecessarily
|
||
|
|
* render both).

|
*
|
||
|
|
* %NFP_NET_CFG_TLV_TYPE_CRYPTO_OPS_RX_SCAN:
|
||
|
|
* Same as %NFP_NET_CFG_TLV_TYPE_CRYPTO_OPS, but crypto TLS does stream scan
|
||
|
|
* RX sync, rather than kernel-assisted sync.
