The firmware parameter LINK_FAIL_TX_CNT maps to the prima configuration file parameter gLinkFailTxCnt and is described as: quote: " If within gLinkFailTimeout period(values is mentioned in msec) if FW doesn't receive acks for gLinkFailTxCnt number of packets, then link will be disconnected." The downstream description sets a minimum value of 1000 a maximum value of 60000 and a default value of 6000, however it appears that unless we actually set this value deliberately firmware defaults it to 0. Setting this value to non-zero results in the firmware doing link monitoring. The working example from downstream paradoxically sets the value to 200, here we opt to set the value to the minimum stipulated in the configuration file 1000. In conjunction with ieee80211_hw_set(wcn->hw, CONNECTION_MONITOR); this change effects offload of link monitoring to the firmware.
