Not yet, but stay tuned. However with your CPUs it will never be=20 possible anyway - if they're the same as on my DP310 (family 6, model 9, = stepping 10, see /proc/cpuinfo) they don't support HW hashing, only=20 encryption. > Any idea how to improve the crypto results?=20 Unfortunately I don't have any other GigE device to test it against.=20 Though on my 100Mbps net it goes fast enough ;-) Anyway - the early DP310 boards were shipped with a buggy BIOS that=20 disabled CPU pipeline. This could be reconfigured by clearing bit 1 of=20 MSR 0x1143. See http://www.logix.cz/michal/devel/viadp310msr/ for a=20 simple program that does it for me. Michal
