2 * Driver for 802.11b cards using RAM-loadable Symbol firmware, such as
3 * Symbol Wireless Networker LA4137, CompactFlash cards by Socket
4 * Communications and Intel PRO/Wireless 2011B.
6 * The driver implements Symbol firmware download. The rest is handled
7 * in hermes.c and orinoco.c.
9 * Utilities for downloading the Symbol firmware are available at
