Well, it turns out that a recent (post r224506) commit seems to have fixed the problem. It hasn't dropped any packets since I upgraded to a kernel with a r228281 version of if_re.c. So, good news. Thanks to those maintaining this driver, rick ps: If you have a need to know which commit fixed this, I can probably test variants to find out. Otherwise, I'm just happy that it's fixed.:-)
