2011-11-11iwlagn: do not use interruptible waitsJohannes Berg
commit effd4d9aece9184f526e6556786a94d335e38b71 upstream. Since the dawn of its time, iwlwifi has used interruptible waits to wait for synchronous commands and firmware loading. This leads to "interesting" bugs, because it can't actually handle the interruptions; for example when a command sending is interrupted it will assume the command completed fully, and then leave it pending, which leads to all kinds of trouble when the command finishes later. Since there's no easy way to gracefully deal with interruptions, fix the driver to not use interruptible waits. This at least fixes the error iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD' I have seen in P2P testing, but it is likely that there are other errors caused by this.

After driver split, extra _agn in priv structure is no needed, remove it. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2011-07-21iwlagn: simplify the bus architectureEmmanuel Grumbach
Call iwl_probe with a ready iwl_bus struct. This means that the bus layer assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to iwl_probe. The device specific struct is allocated together with the common iwl_bus struct by the bus specific layer. The pointer to the aggregate struct is passed to the upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus. The private data given to the PCI subsystem is now iwl_bus and not iwl_priv. Provide bus_* inliners on the way in order to simplify the syntax. Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the external of the bus layer.

2011-07-16iwlagn: move all the ICT related functions to iwl-trans-rx-pcie.cEmmanuel Grumbach
Since the ICT is transport related, move all its functions to the transport layer. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2011-07-16iwlagn: move rx transport functions to iwl-trans-rx-pcie.cEmmanuel Grumbach
Also create a new file: iwl-trans-int-pcie.h which will include the non static functions that are shared among the current pcie transport layer. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
