To compile this driver into the kernel, place the following lines in your kernel configuration file: device ccr device cxgbe

To load the driver as a module at boot time, place the following line in loader.conf(5):

ccr_load="YES"

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-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 crypto(9) consumers such as ktls(4), geli(4), and 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 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.

If an issue is identified with this driver with a supported adapter, email all the specific information related to the issue to <Mt support@chelsio.com>.
