From: Seungyoun Ju <sy39.ju@xxxxxxxxxxx> Slave latency range has been changed in Core Spec. 4.2 by Erratum 5419 of ESR08_V1.0.0. And it should be applied to Core Spec. 4.0 and 4.1. Before: connSlaveLatency <= ((connSupervisionTimeout / connIntervalMax) - 1) After: connSlaveLatency <= ((connSupervisionTimeout / (connIntervalMax*2)) - 1) This patch makes hci_check_conn_params() check the allowable slave latency range using the changed way.
