.Sh NAME
|
|
.Nm ccr
|
|
.Nd "Chelsio T6 crypto accelerator driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device ccr"
|
|
.Ed
|
|
.Pp
|
|
To load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
ccr_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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
|
|
.Xr crypto 4
|
|
and
|
|
.Xr 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

.Pa http://www.chelsio.com/ .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver attaches as a child of an existing Chelsio NIC device and thus
|
|
requires that the
|
|
.Xr cxgbe 4
|
|
driver be active.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports the crypto accelerator engine included on adapters
