The current version of the bcm43xx-softmac driver scans 14 channels, even though channels greater

AFAIK, channel 14 is only allowed in Japan. The attached patch uses the value in bcm->sprom.locale
to set the maximum channel according to the guidelines. This patch is drawn against the 060215 snapshot.
No, this is wrong. read the comment above the
bcm43xx_is_valid_channel() function. This function is only used
to verify, that an integer value is a _technically_ valid channel
number.
There currently is no such thing as regdomain control in the
linux ieee802.11 code. This is a major thing, which needs to be
added. But it must not be added to all the drivers, but the
ieee802.11 common code.
I agree, but placed the patch where I did because I couldn't find any code in ieee80211 that even
sets frequencies.
I will formulate a patch that puts the domain regulations into ieee80211 and submit it to Linville,
then suggest changes to bcm43xx once ieee80211 has been changed.
Incidentally, bcm43xx_is_valid_channel probably should be replaced by ieee80211_is_valid_channel as
follows:
static inline
int bcm43xx_is_valid_channel(struct bcm43xx_private *bcm,
u8 channel)
{
return ieee80211_is_valid_channel(bcm->ieee,channel);
}
Thanks,
Larry
