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⟩.
