Yes. menuconfig has great feature of searching. Just enter "/" key and type phase you're looking for. For example type "/BCMA" and press ENTER. What you want is: Device Drivers -> Broadcom specific AMBA -> BCMA support Device Drivers -> Broadcom specific AMBA -> Support for BCMA on PCI-host bus Device Drivers -> Network device support -> Wireless LAN -> Broadcom 43xx wireless support -> Support for BCMA bus Device Drivers -> Network device support -> Wireless LAN -> Broadcom 43xx wireless support -> Support for HT-PHY (high throughput) devices -- Rafał _______________________________________________ b43-dev mailing list b43-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/b43-dev
