I'm working on replacing a very old box to monitor a very old 10/100 LAN for packet errors. It currently runs on Windows XP with a TurboCap card, configured to capture all traffic including bad frames, which it categorizes by error type and identifies by source if possible.
The new solution will run on some flavor of Linux, and we have tested a number of LAN cards we had around by turning on the rx-fcs and rx-all settings, and running off of a tapped LAN connection so old box and new box should be getting identical data. The only one that was getting the same results as the old one was an obsolete Netgear FA311 card.
Based on documentation, it seems like this should be possible on a few higher end cards, but I was hoping that someone knows for sure that it would and on what cards.
