[PATCH net-next 0/4] New CAIF features

["Sjur Brændeland" <sjur.brandeland@stericsson.com>]

Add feature to aggregate CAIF HSI frames into one large HSI-transfer.
The triggers for starting a HSI transfer are:
Max transfer size reached, timeout or reception of low-latency traffic. 
As long as none of these triggers are met, CAIF-frames will be aggregated.
 
In order to be able to support aggregation and detect low-latency traffic,
CAIF packets are assigned a TC class.
 
In addition we are now allowing other kernel modules to use the HSI interface
while the CAIF interface is closed. The CAIF-HSI interface is changed so that
reference to the HSI interface is held only when CAIF-HSI is in state UP.
Initialization/de-initialization of the HSI HW is performed when the interface
is opened/closed instead of at module load time.

NOTE: This patch-set depends on the patch "caif-hsi: Free flip_buffer at shutdown",
sent in the Bug-fix patch-set.

Regards,
Sjur
