Marc Kleine-Budde says: ==================== pull-request: can-next 2014-08-20 this is a pull request of 10 patches for net-next/master. There is one patch by Wolfram Sang to clean up the build system. Two patches by Stefan Agner that add vf610 support to the flexcan driver. Dong Aisheng add support for bosch's m_can core, which is found in the new freescale ARM SoCs. Sergei Shtylyov improves the rcar_can driver by supporting all input clocks and adding device tree support. The next patch is a small cleanup for the bit rate calculation function by Lad, Prabhakar. And finally a patch by Himangi Saraogi, which converts the mcp251x driver to use dmam_alloc_coherent. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Event timestamp status messages have a variable length, ranging from 1 to 5 words (16 bit words). The current code however requires a minimum message length of sizeof(*phy_txts). In most cases this condition is fulfilled due to padding bytes. However, if several events are signaled in a single message, padding bytes may not be present. For short event timestamp status messages, the length check will fail, and the event timestamp will be dropped.

This patch adds fix_mac_speed() support for Altera socfpga Ethernet controller. Emac splitter is a soft IP core in FPGA system that converts GMII interface from Synopsys mac to RGMII/SGMII interface. This splitter core is an optional IP if user would like to use RGMII/SGMII interface in their system. Software needs to update a register in splitter core when there is speed change.

Trying to disable sriov when VFs are assigned may lead to all kinds of problems. This patch unifies the call in the driver to pci_disable_sriov() and prevents them if some of the PF's child VFs are marked as assigned. [Notice this is a bad scenario either way; User should not reach a point where the OS tries to disable SRIOV when a VF is assigned - but currently there's no way of preventing the user from doing so, and the ill-effect for the driver is smaller this way] Signed-off-by: NYuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: NAriel Elior <Ariel.Elior@qlogic.com> Signed-off-by: NDavid S.

由 Sébastien Barré 提交于
Commit 7a9bc9b8 ("ipv4: Elide fib_validate_source() completely when possible.") introduced a short-circuit to avoid calling fib_validate_source when not needed. That change took rp_filter into account, but not accept_local. This resulted in a change of behaviour: with rp_filter and accept_local off, incoming packets with a local address in the source field should be dropped. Here is how to reproduce the change pre/post 7a9bc9b8 commit: -configure the same IPv4 address on hosts A and B. -try to send an ARP request from B to A. -The ARP request will be dropped before that commit, but accepted and answered after that commit. This adds a check for ACCEPT_LOCAL, to maintain full fib validation in case it is 0. We also leave __fib_validate_source() earlier when possible, based on the same check as fib_validate_source(), once the accept_local stuff is verified.

When writing the driver, I didn't give enough attention to the possible sources of the CAN clock: although the value of the CLKR register was specified by the platform data, the driver only handled one case, that is CAN clock being sourced from the clkp1 clock, the same that clocks the whole CAN module. In order to fix that overlook, we'll have to handle the CAN clock separately from the peripheral clock (however, clkp1 will be specified for a CAN device only once)...

The patch adds the basic CAN TX/RX function support for Bosch M_CAN controller. For TX, only one dedicated tx buffer is used for sending data. For RX, RXFIFO 0 is used for receiving data to avoid overflow. Rx FIFO 1 and Rx Buffers are not used currently, as well as Tx Event FIFO. Due to the message ram can be shared by multi m_can instances and the fifo element is configurable which is SoC dependant, the design is to parse the message ram related configuration data from device tree rather than hardcode define it in driver which can make the message ram sharing fully transparent to M_CAN controller driver, then we can gain better driver maintainability and future features upgrade. M_CAN also supports CANFD protocol features like data payload up to 64 bytes and bitrate switch at runtime, however, this patch still does not add the support for these features.
