Runtime DC calibration was previously conditional. Remove this behaviour, as new devices support runtime DC calibration, while older devices ignore the runtime DC calibration request. This patch addresses low TX throughput issues seen with the 6205. Signed-off-by: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

/**
|
|
* DOC: shared area - role and goal
|
|
*
|
|
* The shared area contains all the data exported by the upper layer to the
|
|
* other layers. Since the bus and transport layer shouldn't dereference
|
|
* iwl_priv, all the data needed by the upper layer and the transport / bus
|
|
* layer must be here.
|
|
* The shared area also holds pointer to all the other layers. This allows a
|
|
* layer to call a function from another layer.
|
|
*
|
|
* NOTE: All the layers hold a pointer to the shared area which must be shrd.
|
|
* A few macros assume that (_m)->shrd points to the shared area no matter
|
|
* what _m is.
|
|
*
|
|
* gets notifications about enumeration, suspend, resume.
|
|
* For the moment, the bus layer is not a linux kernel module as itself, and
|
|
* the module_init function of the driver must call the bus specific
|
|
* registration functions. These functions are listed at the end of this file.
|
|
* For the moment, there is only one implementation of this interface: PCI-e.
|
|
* This implementation is iwl-pci.c

* mac80211 queues, ACs, hardware queues, FIFOs.
|
|
*
|
|
* Cf. http://wireless.kernel.org/en/developers/Documentation/mac80211/queues
|
|
*
|
|
* Mac80211 uses the following numbers, which we get as from it
|
|
* by way of skb_get_queue_mapping(skb):
|
|
*
|
|
* VO 0
|
|
* VI 1
|
|
* BE 2
|
|
* BK 3
|
|
*
|
|
*
|
|
* Regular (not A-MPDU) frames are put into hardware queues corresponding
|
|
* to the FIFOs, see comments in iwl-prph.h. Aggregated frames get their
|
|
* own queue per aggregation session (RA/TID combination), such queues are
|
|
* set up to map into FIFOs too, for which we need an AC->FIFO mapping. In
|
|
* order to map frames to the right queue, we also need an AC->hw queue
|
|
* mapping. This is implemented here.
|
|
*
|
|
* Due to the way hw queues are set up (by the hw specific modules like
|
|
* iwl-4965.c, iwl-5000.c etc.), the AC->hw queue mapping is the identity
|
|
* mapping.
