30.Sh NAME
31.Nm ccr
32.Nd "Chelsio T6 crypto accelerator driver"
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following lines in your
36kernel configuration file:
37.Bd -ragged -offset indeunt
38.Cd "device ccr"
39.Ed
40.Pp
41To load the driver as a
42module at boot time, place the following line in
43.Xr loader.conf 5 :
44.Bd -literal -offset indent
45ccr_load="YES"
46.Ed
47.Sh DESCRIPTION
48The
49.Nm
50driver provides support for the crypto accelerator engine included on
51PCI Express Ethernet adapters based on the Chelsio Terminator 6 ASIC (T6).
52The driver accelerates AES-CBC, AES-CTR, AES-GCM, AES-XTS, SHA1-HMAC,
53SHA2-256-HMAC, SHA2-384-HMAC, and SHA2-512-HMAC operations for
54.Xr crypto 4
55and
56.Xr ipsec 4 .
57The driver also supports chaining one of AES-CBC, AES-CTR, or AES-XTS with
58SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC, or SHA2-512-HMAC for
59encrypt-then-authenticate operations.
60For further hardware information and questions related to hardware
61requirements, see
62.Pa http://www.chelsio.com/ .
63.Pp
64The
65.Nm
66driver attaches as a child of an existing Chelsio NIC device and thus
67requires that the
68.Xr cxgbe 4
69driver be active.
70.Sh HARDWARE
71The
72.Nm
73driver supports the crypto accelerator engine included on adapters
74based on the T6 ASIC:
