Overview: Intel(R) QuickAssist Technology (Intel(R) QAT) provides hardware acceleration for offloading security, authentication and compression services from the CPU, thus significantly increasing the performance and efficiency of standard platform solutions. This commit introduces: - Intel® 4xxx Series platform support. - QuickAssist kernel API implementation update for Generation 4 device. Enabled services: symmetric cryptography and data compression. - Increased default number of crypto instances in static configuration for performance purposes. OCF backend changes: - changed GCM/CCM MAC validation policy to generate MAC by HW and validate by SW due to the QAT HW limitations.

A complete API for offloading these operations is exposed in the kernel and may
|
|
be used by any other entity directly.

In addition to exposing complete kernel API for offloading cryptography and
|
|
compression operations, the
|
|
.Nm
|
|
driver also integrates with
|
|
.Xr crypto 4 ,
|
|
allowing offloading supported cryptography operations to Intel (R) QuickAssist
|
|
Technology (QAT) devices.

|
|
.Sh COMPATIBILITY
|
|
The
|
|
.Nm
|
|
driver replaced previous implementation introduced in
|
|
.Fx 13.0 .
|
|
Current version, in addition to
|
|
.Xr crypto 4
|
|
integration, supports also data compression and exposes a complete API for
|
|
offloading data compression and cryptography operations.
