The ice(4) driver is the driver for the Intel E8xx series Ethernet controllers; currently with codenames Columbiaville and Columbia Park. These new controllers support 100G speeds, as well as introducing more queues, better virtualization support, and more offload capabilities. Future work will enable virtual functions (like in ixl(4)) and the other functionality outlined above. For full functionality, the kernel should be compiled with "device ice_ddp" like in the amd64 NOTES file, and/or ice_ddp_load="YES" should be added to /boot/loader.conf so that the DDP package file included in this commit can be downloaded to the adapter. Otherwise, the adapter will fall back to a single queue mode with limited functionality. A man page for this driver will be forthcoming.
