Beware the Sulfites. Sensitivity to sulfites is common among asthmatics. For me, an allergic reaction can result in a severe asthma attack. Dried fruits are usually responsible for the reactions. As with all processed or manufactured food items, I consistently check labels.
In some rare cases, dropped frames can be caused by an old network adapter driver doing a poor job of handing the high speeds being consumed. It's not a bad idea to just check to see if there are any new drivers for your network adapter, just to be sure.
Most switches could report 801.1q tagged frames as giants and they won't get dropped. This happens if a frames that is coming to the switch is 1518 bytes long + 4 bytes of dot1q = 1522. The switch will strip the tag, report the giant but will still let the frame get in without getting dropped.
