[PATCH] A new 10GB Ethernet Driver by Chelsio Communications A Linux driver for the Chelsio 10Gb Ethernet Network Controller by Chelsio (http://www.chelsio.com). This driver supports the Chelsio N210 NIC and is backward compatible with the Chelsio N110 model 10Gb NICs. It supports AMD64, EM64T and x86 systems.
