I do *not* have "CONFIG_WIRELESS_EXT" anywhere in my (android kernel) .config, but do have CONFIG_WIRELESS=y as well as CONFIG_CFG80211_WEXT=y. Also, I can't see any of the wl1251 drivers from compat-wireless (located in drivers/net/wireless/wl1251) being built at all! Am I missing something? No, don't worry. This is harmless if you don't use WEXT. Just remove the CONFIG_CFG80211_WEXT from your .config and the warning should go away. > On a slightly different note, I also tried to use previous versions of compat-wireless - 3.1.1 as well as 2.6.39-1 - but things got even more hairy.

Sometimes compat-wireless breaks, when syncing with the latest upstream sourcers. If the newest works for you, use that. ;) > The wl1251 drivers are not built here either - drivers/net/wireless/wl1251 is untouched! Any help or advice as to how can I resolve this would very much appreciated, thanks! If this is a recent compat-wireless, then the wl1251 driver was moved to drivers/net/wireless/ti/wl1251. Can you check that? -- Cheers, Luca. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
