This flag is protected by the - * spinlock. All code which touches the hardware should check the - * flag after taking the lock, and if it is set, give up on whatever - * they are doing and drop the lock again. The orinoco_lock() - * function handles this (it unlocks and returns -EBUSY if - * hw_unavailable is non-zero). - */ - -#define DRIVER_NAME "orinoco" - -#include <linux/module.h> -#include <linux/kernel.h> -#include <linux/init.h> -#include <linux/delay.h> -#include <linux/netdevice.h> -#include <linux/etherdevice.h> -#include <linux/ethtool.h> -#include <linux/firmware.h> -#include <linux/suspend.h> -#include <linux/if_arp.h> -#include <linux/wireless.h> -#include <linux/ieee80211.h> -#include <net/iw_handler.h> - -#include <linux/scatterlist.h> -#include <linux/crypto.h> - -#include "hermes_rid.h" -#include "hermes_dld.h" -#include "orinoco.h" - -/********************************************************************/ -/* Module information */ -/********************************************************************/ - -MODULE_AUTHOR("Pavel Roskin <proski@gnu.org> & David Gibson <hermes@gibson.dropbear.id.au>"); -MODULE_DESCRIPTION("Driver for Lucent Orinoco, Prism II based and similar wireless cards"); -MODULE_LICENSE("Dual MPL/GPL"); - -/* Level of debugging.
