I've just installed my first Gigabit NIC, an Intel PRO/1000 MT Desktop Adapter card. Now I've got a few questions about this device and about GBit networking in general. This 32-bit PCI card is currently running fine at 100Mbps while I await the delivery of a GBit switch. It is currently running on a RHL v9 system, but I will be upgrading to RHEL soon. 1. Jumbo frames. How does one specify the MTU size as part of the process of initializing the device? I know that I can specify this using ifconfig in rc.local, but I'm guessing that there is a "proper" way to specify this as part of the system config. 2. Which driver? A driver for this card (it uses the Intel 82541GI controller) is available in the standard Linux kernel as well as in a binary module from Intel. Which of these 2 drivers is preferred? 3. Finally, are there any kinks or gotchas I should aware of in getting optimum performance from this device when my GBit switch arrives? Thanks.
