<p class="Pp">The <code class="Nm">ccr</code> 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 <a class="Xr">crypto(9)</a> consumers such as
<a class="Xr">ktls(4)</a>, <a class="Xr">geli(4)</a>, and
<a class="Xr">ipsec(4)</a>. 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 <span class="Pa">http://www.chelsio.com/</span>.</p>
<p class="Pp">The <code class="Nm">ccr</code> driver attaches as a child of an
existing Chelsio NIC device and thus requires that the
<a class="Xr">cxgbe(4)</a> driver be active.</p>
