코드 linux-4.1 도움말
CONFIG_IWL3945:
Select to build the driver supporting the:
Intel PRO/Wireless 3945ABG/BG Network Connection
This driver uses the kernel's mac80211 subsystem.
In order to use this driver, you will need a microcode (uCode)
image for it. You can obtain the microcode from:
<http://intellinuxwireless.org/>.
The microcode is typically installed in /lib/firmware. You can
look in the hotplug script /etc/hotplug/firmware.agent to
determine which directory FIRMWARE_DIR is set to when the script
runs.
If you want to compile the driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/kbuild/modules.txt>. The
module will be called iwl3945.iwl3945 장치 드라이버 내장
드라이버를 모듈(<M>)로 빌드하는 대신 커널에 내장(<*>)해서 빌드했을 경우, 펌웨어 또한 커널에 빌드해야합니다.

펌웨어
iwlwifi-3945-ucode-15.32.2.9.tgz(또는 이후 버전의) 펌웨어가 필요합니다. 이 펌웨어는 sys-kernel/linux-firmware 꾸러미에 들어있습니다.
root #emerge --ask sys-kernel/linux-firmwareNetwork device names
Network device names eth0, wlan0, etc. as provided by the kernel could be changed on boot (see dmesg) by the /lib/udev/rules.d/80-net-name-slot.rules udev rule.
To keep the classic naming this rule can be overwritten with an equally named empty file in the /etc/udev/rules.d directory:
root #touch /etc/udev/rules.d/80-net-name-slot.rules
