* pcmcia: rework the irq_req_t typedefDominik Brodowski2009-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the irq_req_t typedef'd struct can be re-worked quite easily: (1) IRQInfo2 was unused in any case, so drop it. (2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.

* ipwireless: fix compile failureJames Bottomley2008-07-28
| | | | | | | | | | | | | | | | There's a brown paper bag compile failure introduced by this patch commit a01386924874c4d6d67f8a34e66f04452c2abb69 Author: David Sterba <dsterba@suse.cz> Date: Mon Jul 28 16:53:32 2008 +0200 ipwireless: Preallocate received packet buffers with MRU size Really, it can't ever have been even compile tested. It looks like the closing bracket is in the wrong place, so this is the fix.

* ipwireless: Fix blocked sendingDavid Sterba2008-06-06
| | | | | | | | | | | | | | | | | | | | | | | Packet sending is driven by two flags, tx_ready and tx_queued. It was possible, that there were queued data for sending and hardware was flagged as blocked but in fact it was not. The tx_queued was indicator but should be really a counter else first fragmented packet resets tx_queued flag, but there may be pending packets which do not get sent. New semantics: tx_ready - set, if hw is ready to send packet, no packet is being transferred right now set the flag right at the place where data are copied into hw memory and not earlier without checking if it was succesful tx_queued - count of enqueued packets, including fragments Tested-by: Michal Rokos <michal.rokos@gmail.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* ipwireless: driver for PC Card 3G/UMTS modemDavid Sterba2008-02-07
The device is manufactured by IPWireless. In some countries (for example Czech Republic, T-Mobile ISP) this card is shipped for service called UMTS 4G. It's a piece of PCMCIA "4G" UMTS PPP networking hardware that presents itself as a serial character device (i.e. looks like usual modem to userspace, accepts AT commands, etc).
