NAME

     ccr — Chelsio T6 crypto accelerator driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel
     configuration file:

            device ccr

     To load the driver as a module at boot time, place the following line in loader.conf(5):

           ccr_load="YES"

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-CTR, AES-GCM, AES-XTS, SHA1-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, SHA2-256-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

SUPPORT

     For general information and support, go to the Chelsio support website at:
     http://www.chelsio.com/.

     If an issue is identified with this driver with a supported adapter, email all the specific
     information related to the issue to ⟨support@chelsio.com⟩.
