<M> QorIQ DPAA2 CAAM (DPSECI) driver
• backends / interfaces:
— Freescale CAAM Job Ring driver backend (SEC) - JRI;
this also enables QI (QI depends on JRI)
— QorIQ DPAA2 CAAM (DPSECI) driver - DPSECI
• frontends / crypto algorithms:
— symmetric encryption, AEAD, "stitched" AEAD, TLS;
Register algorithm implementations with the Crypto API
- via JRI (caamalg driver) or Queue Interface as Crypto
API backend - via QI (caamalg_qi drive)
— Register hash algorithm implementations with Crypto
API - hashing (only via JRI - caamhash driver)
— Register public key cryptography implementations with
Crypto API - asymmetric / public key (only via JRI -
caam_pkc driver)
— Register caam device for hwrng API - HW RNG (only
via JRI - caamrng driver)
— QorIQ DPAA2 CAAM (DPSECI) driver - DPSECI
• options: debugging, JRI ring size, JRI interrupt coalescing
Networking support --->
Network option --->
<*> TCP/IP networking
<*> IP: AH transformation
<*> IP: ESP transformation
<*> IP: IPsec transport mode
<*> IP: IPsec tunnel mode
For IPsec support the TCP/IP networking option and
corresponding sub-options should be enabled.
