CCR(4)			     Kernel Interfaces Manual			  CCR(4)

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 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(9)
     consumers such as ktls(4), geli(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-authenti-
     cate 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>.

HISTORY
     The ccr device driver first appeared in FreeBSD 12.0.

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