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
	     device cxgbe

       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 in-
       cluded 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	opera-
       tions  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-authen-
       ticate  operations.  For	further	hardware information and questions re-
       lated 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:

       o   Chelsio T6225-CR
       o   Chelsio T6225-SO-CR
       o   Chelsio T62100-LP-CR
       o   Chelsio T62100-SO-CR
       o   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>.

SEE ALSO
       crypto(4), cxgbe(4), ipsec(4)

HISTORY
       The ccr device driver first appeared in FreeBSD 12.0.

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