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 | |

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). | |
