2014-12-11gianfar: Implement PAUSE frame generation supportMatei Pavaluca
The hardware can automatically generate pause frames when the number of free buffers drops under a certain threshold, but in order to do this, the address of the last free buffer needs to be written to a specific register for each RX queue. This has to be done in 'gfar_clean_rx_ring' which is called for each RX queue. In order not to impact performance, by adding a register write for each incoming packet, this operation is done only when the PAUSE frame transmission is enabled. Whenever the link is readjusted, this capability is turned on or off.

Local flow control options needed in order to resolve the negotiation are incorrectly calculated. Previously 'mii_advertise_flowctrl' was called to determine the local advertising options, but these were determined based on FLOW_CTRL_RX/TX flags which are never set through ethtool. The patch simply translates from ethtool flow options to mii flow options.

2014-12-11capwap: add capwap supportPan Jiafei
CAPWAP stands for Control and Provisioning of Wireless Access Points. CAPWAP is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points. There are three drivers in Kernel Space: CAPWAP Domain driver, CAPWAP Bridge driver and CAPWAP Tunnel driver. CAPWAP Domain Driver implements configuration for CAPWAP Domain, including PCD configuration and FQs setup. User must configure and initialize CAPWAP domain before CAPWAP Tunnel and CAPWAP Bridge works. CAPWAP Tunnel Driver is a misc device driver, which registers four misc devices for four CAPWAP tunnels: fsl-capwap-ctrl-dtls, fsl-capwap-ctl-n-dtls, fsl-capwap-data-dtls, fsl-capwap-data-n-dtls. The misc device provides file-operation to transmit/receive DTLS/non-DTLS packets. For example, read from the device fsl-capwap-ctrl-dtls can receive DTLS control packet; Write to the device fsl-capwap-ctrl-dtls can transmit DTLS control packet. The CAPWAP Bridge Driver is also a misc device driver; it can bridge packets between PCIe NIC and CAPWAP data tunnels. To support capwap drivers, there should be a shared ethernet port in dts file to use as CAPWAP Ethernet port.

2014-12-11can: flexcan: put TX mailbox into TX_INACTIVE mode after tx-completeMarc Kleine-Budde
After sending a RTR frame the TX mailbox becomes a RX_EMPTY mailbox. To avoid side effects when the RX-FIFO is full, this patch puts the TX mailbox into TX_INACTIVE mode in the transmission complete interrupt handler. This, of course, leaves a race window between the actual completion of the transmission and the handling of tx-complete interrupt. However this is the best we can do without busy polling the tx complete interrupt.

Workaround: The workaround consists of two extra steps after setting up a message for transmission: Step 8: Reserve the first valid mailbox as an inactive mailbox (CODE=0b1000). If RX FIFO is disabled, this mailbox must be message buffer 0. Otherwise, the first valid mailbox can be found using the "RX FIFO filters" table in the FlexCAN chapter of the chip reference manual.

2014-12-11can: Unify MTU settings for CAN interfacesOliver Hartkopp
CAN interfaces only support MTU values of 16 (CAN 2.0) and 72 (CAN FD). Setting the MTU to other values is pointless but it does not really hurt. With the introduction of the CAN FD support in drivers/net/can a new function to switch the MTU for CAN FD has been introduced. This patch makes use of this can_change_mtu() function to check for correct MTU settings also in legacy CAN (2.0) devices.

2014-12-11can: flexcan: fix transition from and to freeze mode in chip_{,un}freezeMarc Kleine-Budde
This patch factors out freeze and unfreeze of the CAN core into seperate functions. Experiments have shown that the transition from and to freeze mode may take several microseconds, especially the time entering the freeze mode depends on the current bitrate. This patch adds a while loop which polls the Freeze Mode ACK bit (FRZ_ACK) that indicates a successfull mode change. If the function runs into a timeout a error value is returned.

2014-12-11gianfar: Exclude SRAM alloc from non-PPC (ARM)Claudiu Manoil
Allocation of Buffer Descriptors to SRAM is not supported by the ARM based LS1 platform. The CACHE_SRAM feature is PPC specific (mpc85xx SoC family more exactly). The mpc85xx CACHE_SRAM driver lies in the PPC architecture folders, so the API calls in gianfar must be excluded from non-PPC builds, otherwise obviously there will be compile errors on ARM (LS1).
