The purpose of beacon filters is quote: /* When beacon filtering is enabled, firmware will * analyze the selected beacons received during BMPS, * and monitor any changes in the IEs as listed below. * The format of the table is: * - EID * - Check for IE presence * - Byte offset * - Byte value * - Bit Mask * - Byte reference */ The default downstream firmware filter table looks something like this: tBeaconFilterIe gaBcnFilterTable[12] = { { WLAN_EID_DS_PARAMS, 0u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_ERP_INFO, 0u, { 0u, 0u, 248u, 0u } }, { WLAN_EID_EDCA_PARAM_SET, 0u, { 0u, 0u, 240u, 0u } }, { WLAN_EID_QOS_CAPA, 0u, { 0u, 0u, 240u, 0u } }, { WLAN_EID_CHANNEL_SWITCH, 1u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_QUIET, 1u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_HT_OPERATION, 0u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_HT_OPERATION, 0u, { 1u, 0u, 248u, 0u } }, { WLAN_EID_HT_OPERATION, 0u, { 2u, 0u, 235u, 0u } }, { WLAN_EID_HT_OPERATION, 0u, { 5u, 0u, 253u, 0u } }, { WLAN_EID_PWR_CONSTRAINT, 0u, { 0u, 0u, 0u, 0u } }, { WLAN_EID_OPMODE_NOTIF, 0u, { 0u, 0u, 0u, 0u } } }; Add in an equivalent filter set as present in the downstream Linux driver. For now omit the beacon filter "rem" command as downstream does not have an explicit call to that SMD command. The filter mask should only count when we are inside BMPS anyway. Replicating the downstream ability to program the filter table gives us scope to add and remove elements in future. For now though this patch makes the rote-copy of the downstream Linux beacon filter table, which we can tweak as desired from now on.
