The id_table allows hotplug (along with pcmciautils [1]) to load the driver without the need for the pcmcia-cs cardmgr daemon. The id_table was generated from the CVS version of hostap_cs.conf using a script borrowed from Dominik Brodowski. I have removed any duplicate entries, but I have only been able to test the functionality of the patch with a Linksys WPC11v3.

A simple fix would be to use double cast from pointer to long and then to int (and vice versa when int is passed as a pointer). But I prefer a slightly longer patch. I believe that whenever an argument can hold both a pointer and an integer, it should be declared long. long can hold both pointers and integers (except win64, but we are not coding for Windows), it can be cast to both of them and it's never assumed to be a valid pointer, which could be useful for some automatic code checkers.

This resulted in the power save code corrupting the magic value in beginning of the buffer and TX code dropping the power saved packets because of this for the case where STAs send PS-Poll frames with PwrMgmt flag set. This patch modifies the power save code to use the same struct hostap_skb_tx_data as rest of the TX path in order to avoid corrupting the data in skb->cb. In addition, this patch reorders fields in the structure and makes them use smaller types in order to make the structure fit in skb->cb on 64-bit hosts.

RX side could possibly be made to work reliably. Even though DMA support would be very useful for saving host CPU (from about 40% to 5-10% when operating at maximum throughput), it seems to be best to just remove this code finally. The implementation has always been commented out by default and has received very limited testing. The code may have already been broken number of times and I don't have much interested in trying to verify whether it works or not. Getting this out makes it easier to maintain the driver and allows some cleanups that have been partly postponed because of this experimental bus master/DMA code.

This removes unneeded #ifdef's and as such, is a step towards making it possible to share objects for hostap_hw.c and hostap_download.c with cs/pci/plx drivers without having to compile and link the same code separately for each one.

This could trigger a NULL pointer dereference in prism2_pccard_card_present() that assumed that local->hw_priv is always set (and it should have been). Fix this by setting local->hw_priv before registering the interrupt handler.
