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
