Authors

       The ccr driver was written by John Baldwin <jhb@FreeBSD.org>.

Debian                                            June 3, 2019                                            CCR(4)

Description

       The  ccr  driver  provides  support  for  the  crypto accelerator engine included on PCI Express Ethernet
       adapters based on the Chelsio Terminator 6 ASIC (T6).  The driver accelerates AES-CBC, AES-CCM,  AES-CTR,
       AES-GCM,  AES-XTS, SHA1, SHA2-224, SHA2-256, SHA2-384, SHA2-512, SHA1-HMAC, SHA2-224-HMAC, SHA2-256-HMAC,
       SHA2-384-HMAC, and SHA2-512-HMAC operations  for  crypto(4)  and  ipsec(4).   The  driver  also  supports
       chaining one of AES-CBC, AES-CTR, or AES-XTS with SHA1-HMAC, SHA2-224-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,
       or  SHA2-512-HMAC  for  encrypt-then-authenticate  operations.   For  further  hardware  information  and
       questions related to hardware requirements, see http://www.chelsio.com/.

       The ccr driver attaches as a child of an existing Chelsio NIC device and thus requires that the  cxgbe(4)
       driver be active.

Hardware

       The ccr driver supports the crypto accelerator engine included on adapters based on the T6 ASIC:

       •   Chelsio T6225-CR
       •   Chelsio T6225-SO-CR
       •   Chelsio T62100-LP-CR
       •   Chelsio T62100-SO-CR
       •   Chelsio T62100-CR

History

       The ccr device driver first appeared in FreeBSD 12.0.
