Move all the PCI-E specific transport files to
be iwl-trans-pcie*; specifically iwl-trans.c
which is really iwl-trans-pcie.c.

Emmanuel Grumbach 1dd9124e29 iwlagn: provide data after WARN_ON
From time to time, we hit a WARN_ON in iwl_mac_remove_interface.
This basically means that we got out of sync with mac80211: the vif
we hold differs from the vif 80211 passes as parameter. Try to get
some data that will help to debug this.

Emmanuel Grumbach 39644e9ac5 iwlagn: unmap cmd queue's tfds as BIDI
If the driver is unloaded while there is still a host command in
flight, its tfd will be freed by iwl_tx_queue_free.
This function is called for both types of queues: Tx queues and cmd
queue. This didn't take in count the fact that in Tx queues, tfds are
mapped as TO_DEVICE (besides the first TB), whereas in cmd queue, all
TBs are mapped as BIDI.

Hence, tx_queue_free unmapped the second (and higher) TB of each tfd
in the cmd queue as TO_DEVICE, whereas they must be freed as BIDI.
This means that if a multi TFD is in flight while we unload the
driver (which is quite unlikely but can happen), we will get the
warning below.

This patch fixes this.

Emmanuel Grumbach 17a68dd7bc iwlagn: warn about buggy fw that doesn't set SEQ_RX_FRAME
The way we check if there is host command that should be reclaimed is
way too complicated. We should have a clear indication from the fw.
The fw is expected to set the SEQ_RX_FRAME bit if the frame was
originated by the fw which indicates to the driver that there is no
host command to free.
Somehow, there seem to have been buggy fw out there, hence the very
old comment.

This code checks if we have still buggy fw out there.
