I think that+ handle->md.stat.ps_drop += (handle->md.proc_dropped - if_dropped);and+ stats->ps_drop = handle->md.stat.ps_drop;are wrong, because ps_drop is supposed to reflect the number of packets dropped by the packet capture mechanism because they arrived faster than the app could consume them, but not the number of packets dropped by the adapter or adapter driver before they even made it to the capture mechanism. ps_ifdrop is for the latter (and the comment about it being unimplemented is false on Tru64 UNIX, for example, so don't let that comment scare you off).
Yeah, my second patch changed it to ps_ifdrop. Unfortunately, the spam blocker always catches git patches because they have 'index[random numbers]' in them, so it doesn't show up on the mailing list til someone approves it... :) Dustin -- Innovation is just a problem away
