2014-09-05dpaa_eth: merge recycle and confirmation queuesMarian Rotariu
In FMan v3, special transmission queues, called recycle queues, were created because it was believed that the FCO flag from the FD is not enough to differentiate between frames that are recyclable and those who are not. The frame queue flags were used to signal the BMI to release the buffers back to the default buffer pool. The last findings and FMan improvements permit recycling activation only by using FD fields. With this patch, the recycling frame queues are not needed anymore. This patch also removes the code dependency on the FMan version and improves TCP traffic in forwarding scenarios due to single transmission queues, reducing the out-of-order segments.

2014-06-17dpaa_eth: fix CSUM for maclessMarian Rotariu
Macless is a type of generic DPAA driver that does not know its immediate underlying HW block on TX. It can be connected with an OH port, a TX port, directly with another Macless driver in Macless-Macless scenario or with another HW module. Because not all HW modules know how to calculate CSUM, Macless triggers software computation of the CSUM. If another HW block modifies the frame it needs to trigger the Parser to recalculate CSUM. This patch adds different default values for the parse results structure that forbids the Parser from doing CSUM validation or computation. The _DTC and _RPD flags inside the Frame Descriptor are enabled together. This is the only way to deactivate HW CSUM in all the flows.

2014-06-13onic: add periodic drainingMarian Rotariu
In unidirectional flows, like UDP, generated by kernel through onic driver, the traffic can block because of numerous frames that are in HW and not released fast enough by the driver. This patch adds a timer that releases frames periodically, regardless of the reception and transmission rates. This mechanism was chosen instead of the workqueue mechanism because of its higher priority, larger than RX and TX procedures.

2014-06-03onic: increase frequency of drainingMarian Rotariu
The draining function will be executed when each CPU has added more than 8 buffers in the draining pool. In some conditions, the sock buffers waits for the Ethernet driver to release the buffer in order to continue its transmission. To avoid memory depletion in the sock buffers, the Ethernet driver will release faster the received skb from the stack. This patch makes onic to call the drain procedure on RX path also even if there is only one buffer in the bpool.

2014-05-09gianfar: Avoid unnecessary reg accesses in adjust_link()Claudiu Manoil
For phy devices that don't issue interrupts upon link state changes, phylib polls the link state resulting in repeated calls to adjust_link(), even if the link state didn't change. As a result, some mac registers are repeatedly read and written with the same values, which is not ok. To fix this, adjust_link() has been refactored to check first whether the link state has changed and to take action only if needed, updating mac registers and local state variables. The 'new_state' local flag, set if one of the link params changed (link, speed or duplex), has been rendered useless and removed by this refactoring.

2014-05-09gianfar: Use netif_device_{detach,attach}() around resetClaudiu Manoil
We need to keep the TX queues stopped throughout a reset, without triggering the TX watchdog and regardless of the link state. Given the way the watchdog works, the proper way to do this is to use netif_device_{detach,attach}() just as we do around suspend/resume. netif_device_detach() can be called to stop TX queues in a control operation other than ndo_stop, and in our case this is insured by testing the driver's RESETTING state flag. napi_disable() is called before the stopping the TX queues to make sure that the poll function is not running, and therefore there can be no netif_wake_queue() calls. (Inspired by sfc.)

2014-05-09asf_gfar: Patch to fix the crash seen in ifup for bsc9132.Sandeep Malik
ASF uses two TX queues to avoid contention. BSC9132 even though having controller which can support two groups was having the DTS file written for one group. To fix this we allow ASF to override the default tx queue mapping with the "fsl,tx-bit-map" value given in the DT. This patch resolves the crash seen in case of bsc9132 board when the network interface is up and trying to xmit the packet.

2014-05-08gianfar: Add BD rings allocation to L2 SRAMClaudiu Manoil
When this option is enabled the driver will try to allocate the buffer descriptors (BDs) to the L2 SRAM memory, using the powerpc/85xx cache-sram support API for the P1/P2 QorIQ platforms. For this to work, the size and address of the SRAM region must be provided as kernel boot params. Should the attempt to allocate in L2 SRAM fail, the driver falls back to normal allocation of BDs as before (to DDR). The gfar_l2sram_en driver module param is provided to allow to disable the allocation to L2 SRAM at driver level (enabled by default).
