Remove some 5 GHz related code.

Hi Michael and all,

looks good.

Acked-by: Martin Kaiser <[email protected]>


Two comments unrelated to your patch: I guess that DSConfig is the
channel number, those two drivers have a misleading comment:

3 F m DSConfig
drivers/staging/r8188eu/include/wlan_bssdef.h
struct:ndis_802_11_config
u32 DSConfig; /* Frequency, units are kHz */
4 F m DSConfig drivers/staging/rtl8712/wlan_bssdef.h
struct:NDIS_802_11_CONFIGURATION
u32 DSConfig; /* Frequency, units are kHz */


The rtw_wx_get_name function has a similar check
if (pcur_bss->Configuration.DSConfig > 14).

But when Larry adds cfg80211 support, I guess all IW_HANDLER()s will
become obsolete...

Best regards,
Martin
