its value once per ifconfig run. Use Sam's new callback operation to set it when everything is done. The purpose for this is that if you did something like ifconfig bge0 media 100baseTX mediaopt full-duplex multiple times it would end up causing the PHY to re-sync since it would send the IOCTLs: ifconfig bge0 media 100baseTX -mediaopt full-duplex ifconfig bge0 media 100baseTX mediaopt full-duplex This would cause the PHY to be updated twice even though there really wasn't any change since the check in sys/net/if_media.c would always fail. Caveat is that this doesn't fix the case of: ifconfig bge0 media autoselect etc. since in sys/net/if_media.c it forces an autoselect to go through the entire process in ifmedia_ioctl :-( : /* * If no change, we're done. * XXX Automedia may invole software intervention. * Keep going in case the the connected media changed. * Similarly, if best match changed (kernel debugger?). */ if ((IFM_SUBTYPE(newmedia) != IFM_AUTO) && (newmedia == ifm->ifm_media) && (match == ifm->ifm_cur)) return 0; Briefly looked at by: sam
