The 82557 has a receive side bug that can cause it to stop receiving, but this isn't caused by it being 'overwhelmed". The problem is supposed to only occur when using them in 10Mbps mode, although it can happen if the link changes state as well. The FreeBSD driver has a work-around for this problem and it the bug shouldn't exist in newer Intel chips in any case. -DG D.G.Lawrence Download Technologies, Inc. - http://www.downloadtech.com - (866) 399 8500 TeraSolutions, Inc. - http://www.terasolutions.com - (503) 288 9544 The FreeBSD Project - http://www.freebsd.org Pave the road of life with opportunities.
