Kirill> please read comments in /usr/src/sys/pci/if_rl.c It's worth noting that there's a scale to all this. The driver comments imply that the card will push 100Mb if you have enough power in the CPU ... defined as 400Mhz. Given the price of this card ... and the fact that less-than-400Mhz CPU's are rather rare, and that this is only an issue for high bandwidth applications ... the rl cards might fit for you. We use them extensively in workstations... even diskless. The reason being that with modern processors, they perform adequately ... and although they take up extra CPU ... CPUs are rather under-utilized resources in most workstations.
