John Baldwin 37e98e0dda Add 'device cxgbe' explicitly in the synopsis.
ccr depends on symbols exported by the cxgbe driver as well as having
a runtime dependency.  While the runtime depenency was noted in the
manpage already, the compile-time dependency wasn't as clear.

.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"
.Cd "device cxgbe"
.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
based on the T6 ASIC:
