Looking for tuning beacon interval on BCM4329

Looking for tuning beacon interval on BCM4329

[Hao Han]

Dear All,

Using BCM4329 driver, my Nexus One can serve in AP mode with default
beacon interval of 100ms. I am really hoping to be able to tuning such
a value for some tests. After downloading and searching the source
code from

http://android.git.kernel.org/?p=kernel/msm.git;a=tree;f=drivers/net/wireless/bcm4329;h=01f09252ff9b80379e6db6dbb22af4fcba004982;hb=HEAD

I cannot find any place where the default value of beacon interval is
assgined to 100ms. All beacon related lines are parsed in the
following

./include/wlioctl.h:98:	uint16		beacon_period;		
./include/wlioctl.h:966:#define VNDR_IE_BEACON_FLAG	0x1
./include/wlioctl.h:1103:	uint32	rxbeaconmbss;	
./include/wlioctl.h:1105:	uint32	rxbeaconobss;	
./include/proto/802.11.h:86:#define DOT11_MIN_BEACON_PERIOD		1	
./include/proto/802.11.h:87:#define DOT11_MAX_BEACON_PERIOD		0xFFFF	
./include/proto/802.11.h:224:	uint16			beacon_interval;
./include/proto/802.11.h:746:#define FC_SUBTYPE_BEACON		8	
./include/proto/802.11.h:802:#define FC_BEACON	FC_KIND(FC_TYPE_MNG,
FC_SUBTYPE_BEACON)
./include/proto/802.11.h:862:#define DOT11_MNG_BEACON_INT_LEN	2	
./include/proto/bcmevent.h:92:#define WLC_E_BEACON_RX		15	
./dhd_common.c:548:		{WLC_E_BEACON_RX, "BEACON_RX"},
./dhd_common.c:693:	case WLC_E_BEACON_RX:
./dhd_common.c:1311:	uint32 listen_interval = LISTEN_INTERVAL; /*
Default Listen Interval in Beacons */
./dhd_common.c:1398:	/* Setup timeout if Beacons are lost and roam is
off to report link down */
./wl_iw.c:8022:	wstats->miss.beacon = 0;

Any feedback would be extremely appreciated :)

Thanks,
Hao

Hi Hao,

I am afraid there is no interface exposed for the configuration of 
beacon interval.
