Actually, 'tsf_hi' is used to store the complete tsf value as its data type is u64. This value is pass to the cfg80211_inform_bss() as it is. So the conversion of 'tsf_hi' to 32 bit is not required in this case. >> + info->cap_info = le16_to_cpu(mgt->u.beacon.capab_info); >> + info->beacon_period = le16_to_cpu(mgt->u.beacon.beacon_int); >> + info->tsf_hi = le64_to_cpu(mgt->u.beacon.timestamp); >> + info->tsf_lo = (u32)info->tsf_hi; > Perhaps this should be > > network_info->tsf_hi = le64_to_cpu(mgt->u.beacon.timestamp) >> > 32; > > or > > network_info->tsf_hi = upper_32_bits(le64_to_cpu(...)); > network_info->tsf_lo = lower_32_bits(le64_to_cpu(...)); > > _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
