gigabit ethernet adapters. This includes two single port cards (single mode and multimode fiber) and two dual port cards (also single mode and multimode fiber). SysKonnect is currently the only vendor with a dual port gigabit ethernet NIC. The ports on dual port adapters are treated as separate network interfaces. Thus, if you have an SK-9844 dual port SX card, you should have both sk0 and sk1 interfaces attached. Dual port cards are implemented using two XMAC II chips connected to a single SysKonnect GEnesis controller. Hence, dual port cards are really one PCI device, as opposed to two separate PCI devices connected through a PCI to PCI bridge. Note that SysKonnect's drivers use the two ports for failover purposes rather that as two separate interfaces, plus they don't support jumbo frames. This applies to their Linux driver too. :) Support is provided for hardware multicast filtering, BPF and jumbo frames. The SysKonnect cards support TCP checksum offload however this feature is not currently enabled (hopefully it will be once we get checksum offload support). There are still a few things that need to be implemeted, like the ability to communicate with the on-board LM80 voltage/temperature monitor, but I wanted to get the driver under CVS control and into -current so people could bang on it. A big thanks for SysKonnect for making all their programming info for these cards (and for their FDDI and token ring cards) available without NDA (see www.syskonnect.com).
