I have made a small patch for the zd1211rw driver which uses the boundry channels of the regulatory domain, rather than the hard coded values of 1 & 11. Signed-off-by: Holden Karau <[EMAIL PROTECTED]> http://www.holdenkarau.com --- I'm not entirely sure how useful this patch is, but it seems like a good idea. If its totally misguided, let me know :-) In case the patch gets mangled I've put it up at http://www.holdenkarau.com/~holden/projects/zd1211rw/zd1211rw-use-geo-for-channels.patch And now for the patch: --- a/drivers/net/wireless/zd1211rw/zd_chip.c 2006-10-23 10:07:39.000000000 -0400 +++ b/drivers/net/wireless/zd1211rw/zd_chip.c 2006-10-23 10:41:51.000000000 -0400 @@ -38,6 +38,8 @@ void zd_chip_init(struct zd_chip *chip, mutex_init(&chip->mutex); zd_usb_init(&chip->usb, netdev, intf); zd_rf_init(&chip->rf); + /* The chip needs to know which geo it is in */ + chip->geo = ieee80211_get_geo(zd_mac_to_ieee80211(zd_netdev_mac(netdev))); } void zd_chip_clear(struct zd_chip *chip) @@ -606,14 +608,17 @@ static int patch_6m_band_edge(struct zd_ { CR128, 0x14 }, { CR129, 0x12 }, { CR130, 0x10 }, { CR47, 0x1e }, }; + struct ieee80211_geo *geo = chip->geo; if (!chip->patch_6m_band_edge || !chip->rf.patch_6m_band_edge) return 0; - /* FIXME: Channel 11 is not the edge for all regulatory domains. */ - if (channel == 1 || channel == 11) + /* Checks the channel boundry of the region */ + dev_dbg_f("checking boundry == %d || %d\n" , 1 , geo->bg_channels); + if (channel == 1 || channel == geo->bg_channels) ioreqs[0].value = 0x12; + dev_dbg_f(zd_chip_dev(chip), "patching for channel %d\n", channel); return zd_iowrite16a_locked(chip, ioreqs, ARRAY_SIZE(ioreqs)); } --- a/drivers/net/wireless/zd1211rw/zd_chip.h 2006-10-23 10:07:39.000000000 -0400 +++ b/drivers/net/wireless/zd1211rw/zd_chip.h 2006-10-23 10:39:08.000000000 -0400 @@ -21,6 +21,8 @@ #include "zd_types.h" #include "zd_rf.h" #include "zd_usb.h" +#include "zd_ieee80211.h" +#include <linux/wireless.h> /* Header for the Media Access Controller (MAC) and the Baseband Processor * (BBP).
