We need to have the promiscus mode enabled for older
chipset(ie rule out many frames being filtered in the
hardware itself)if 'FIF_OTHER_BSS' flag is set, when we
start the mesh mode. Fix this by enabling promiscus
mode for all chipsets whose macversion <= AR9160
chipsets. This should fix

John, kindly drop this. Had resent the v2 with proper author
name (Thomas) who suggested the change.
