Its fairly new, and the future of support for it under free OSes looks grim. its basically got an arm core in it that does all the magic. rumor has it that there are lots of nasty nasty patents involved in the thing and 3com isn't too excited about giving out docs (or, even worse, are under patent licensing agreements that forbid them from doing so). I called 3com and asked to get a list of patents associated with the card but all they gave me were the 3com ones on doing typical ethernet interface stuff.. no magical driver interraction patents. I'd love to get more conclusive information. It looks like a fun little toy. in differnet news, the most recently released eepro100 linux driver from intel shows how to do csum offloading and shows how they load microcode to do interrupt mitigation and such. one would hope that they could now actually admit to the features and release docs, but.. :( Its worth noting that vendors like syskonnect actually want to _help_ people write drivers. they should be encouraged :) -- zach To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
