JDR is selling these as a DFI card; the prices are attractive. One of the big problems for driver writers seems to be that many chips require 32-bit alignment of packets (or parts thereof). How hard would it be to adapt FreeBSD's network stack to satisfy this requirement automatically? --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
