====================
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.

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.

bnx2x: Start utilizing 7.10.51
This series will enable bnx2x to start utlizing its 7.10.51 FW.
In addition, it will also add timestamping support, as well as a couple
of routine semantic cleanups.

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]

It's possible there's a bad chip configuration which will result with
PCIe IOV capabilities, but with no available interrupts for VFs.
In such case, we want to gracefully prevent the PF from initializing its
IOV capabilities rather than encounter difficulties further along the way.

The bnx2x panic dump spills a lot of information from the driver's
fastpath, but may be called while some of the fastpath is uninitialized.
This patch verifies that pointers are already allocated before dereferencing
them to prevent possible kernel panics.

This adds a PHC to the bnx2x driver. Driver supports timestamping send/receive
PTP packets, as well as adjusting the on-chip clock.
The driver has been tested with linuxptp project.

- (L2) In some multi-function configurations, inter-PF and inter-VF
Tx switching is incorrectly enabled.
- (L2) Wrong assert code in FLR final cleanup in case it is sent not
after FLR.
- (L2) Chip may stall in very rare cases under heavy traffic with FW GRO
enabled.
- (L2) VF malicious notification error fixes.
- (L2) Default gre tunnel to IPGRE which allows proper RSS for IPGRE packets,
L2GRE traffic will reach single queue.
- (FCoE) Fix data being placed in wrong buffer when corrupt FCoE frame is
received.
- (FCoE) Burst of FIP packets with destination MAC of ALL-FCF_MACs
causes FCoE traffic to stop.

The use of "rcu_assign_pointer()" is NULLing out the pointer.
According to RCU_INIT_POINTER()'s block comment:
"1. This use of RCU_INIT_POINTER() is NULLing out the pointer"
it is better to use it instead of rcu_assign_pointer() because it has a
smaller overhead.

The "rcu_dereference()" call is used directly in a condition.
Since its return value is never dereferenced it is recommended to use
"rcu_access_pointer()" instead of "rcu_dereference()".
Therefore, this patch makes the replacement.
