This looks like a very interesting project. I'm quite interested in seeing the idam(4) driver as I'm working on a driver for the hardware crypto engine in the 88F5182 (and later the 88F6xxx I hope) and it'd be much improved by DMA support. Good luck, Kristof _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
