The interrupt handler is written such - * that everything it does is safe without a lock: chiefly this means - * that the Rx path uses one of the Hermes chipset's BAPs while - * everything else uses the other. - * - * For the moment access to the device statistics from the interrupt - * handler is unsafe - we just put up with any resulting errors in the - * statisics. FIXME: This should probably be changed to store the - * stats in atomic types. - * - * EXCEPT that we don't want the irq handler running when we actually - * reset or shut down the card, because strange things might happen - * (probably the worst would be one packet of garbage, but you can't - * be too careful). For this we use __dldwd_stop_irqs() which will set - * a flag to disable the interrupt handler, and wait for any - * outstanding instances of the handler to complete. THIS WILL LOSE - * INTERRUPTS! so it shouldn't be used except for resets, when we - * don't care about that.*/ - -/* - * Tentative changelog... - * - * v0.01 -> v0.02 - 21/3/2001 - Jean II - * o Allow to use regular ethX device name instead of dldwdX - * o Warning on IBSS with ESSID=any for firmware 6.06 - * o Put proper range.throughput values (optimistic) - * o IWSPY support (IOCTL and stat gather in Rx path) - * o Allow setting frequency in Ad-Hoc mode - * o Disable WEP setting if !has_wep to work on old firmware - * o Fix txpower range - * o Start adding support for Samsung/Compaq firmware - * - * v0.02 -> v0.03 - 23/3/2001 - Jean II - * o Start adding Symbol support - need to check all that - * o Fix Prism2/Symbol WEP to accept 128 bits keys - * o Add Symbol WEP (add authentication type) - * o Add Prism2/Symbol rate - * o Add PM timeout (holdover duration) - * o Enable "iwconfig eth0 key off" and friends (toggle flags) - * o Enable "iwconfig eth0 power unicast/all" (toggle flags) - * o Try with an intel card.

FIXME: This should probably be changed to store the + * stats in atomic types. + * + * EXCEPT that we don't want the irq handler running when we actually + * reset or shut down the card, because strange things might happen + * (probably the worst would be one packet of garbage, but you can't + * be too careful). For this we use __dldwd_stop_irqs() which will set + * a flag to disable the interrupt handler, and wait for any + * outstanding instances of the handler to complete.
