1da177e4
LT		 50 * o Handle de-encapsulation within network layer, provide 802.11
51 * headers (patch from Thomas 'Dent' Mirlacher)
1da177e4
LT		 52 * o Fix possible races in SPY handling.
53 * o Disconnect wireless extensions from fundamental configuration.
54 * o (maybe) Software WEP support (patch from Stano Meduna).
55 * o (maybe) Use multiple Tx buffers - driver handling queue
56 * rather than firmware.

59/* Locking and synchronization:
60 *
61 * The basic principle is that everything is serialized through a
62 * single spinlock, priv->lock. The lock is used in user, bh and irq
63 * context, so when taken outside hardirq context it should always be
64 * taken with interrupts disabled. The lock protects both the
65 * hardware and the struct orinoco_private.
66 *
67 * Another flag, priv->hw_unavailable indicates that the hardware is
68 * unavailable for an extended period of time (e.g. suspended, or in
69 * the middle of a hard reset). This flag is protected by the
70 * spinlock. All code which touches the hardware should check the
71 * flag after taking the lock, and if it is set, give up on whatever
72 * they are doing and drop the lock again. The orinoco_lock()
73 * function handles this (it unlocks and returns -EBUSY if
74 * hw_unavailable is non-zero).
