Hello, Adrian Chadd <adrian@freebsd.org> wrote: > So what's the value of txchainmask and rxchainmask from the EEPROM? > before things get overridden? > > I'd like to figure out what that changed. In both before and after applying the patch, sc->txchainmask=1, sc->rxchainmask=3, ntxsteams=1. I think that 1st breakage introduced by r258030 in the function iwn_set_link_quality() was already fixed by r258085. 2nd breakage introduced by r258035 seems to be fixed by the patch. Because 2nd breakage was introduced before 1st breakage was fixed, we faced to a difficulty tracking down the problem. I don't know a meaning of a parameter .calib_need, but it is something wrong and it is corrected by the patch. -- Kaho Toshikazu
