Mellanox, mlx5 E-Switch updates 2017-12-19
This series includes updates for mlx5 E-Switch infrastructures,
to be merged into net-next and rdma-next trees.
Mark's patches provide E-Switch refactoring that generalize the mlx5
E-Switch vf representors interfaces and data structures. The serious is
mainly focused on moving ethernet (netdev) specific representors logic out
of E-Switch (eswitch.c) into mlx5e representor module (en_rep.c), which
provides better separation and allows future support for other types of vf
representors (e.g. RDMA).
Gal's patches at the end of this serious, provide a simple syntax fix and
two other patches that handles vport ingress/egress ACL steering name
spaces to be aligned with the Firmware/Hardware specs.
V1->V2:
- Addressed coding style comments in patches #1 and #7
- The series is still based on rc4, as now I see net-next is also @rc4.
V2->V3:
- Fixed compilation warning, reported by Dave.
Please pull and let me know if there's any problem.

Each vport has its own root flow table for the ACL flow tables and root
flow table is per namespace, therefore we should create a namespace for
each vport.

Now that we don't store type dependent data in struct mlx5_eswitch_rep
we can create a generic interface, and representor type.
struct mlx5_eswitch_rep will store an array of interfaces, each
interface is used by a different representor type.
Once we moved to a more generic interface, rdma driver representors can
be added and utilize the same mechanism as the Ethernet driver
representors use.

Ethernet representors have a need to store data which is applicable
only for them. Create a priv void pointer in struct mlx5_eswitch_rep
and move mlx5e to store the relevant data there. As part of this change
we also initialize rep_if in mlx5e_rep_register_vf_vports() as otherwise the
E-Switch code will copy a priv value which is garbage.
We also rename mlx5_eswitch_get_uplink_netdev() to
mlx5_eswitch_get_uplink_priv() and make it return void *.
This way E-Switch code doesn't need to deal with net devices and
we leave the task of getting it to mlx5e.

Patches for 4.16 that are dependent on patches sent to 4.15-rc.
These are small clean ups for the vmw_pvrdma and i40iw drivers.
* 'from-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git:
RDMA/vmw_pvrdma: Remove usage of BIT() from UAPI header
RDMA/vmw_pvrdma: Use refcount_t instead of atomic_t
RDMA/vmw_pvrdma: Use more specific sizeof in kcalloc
RDMA/vmw_pvrdma: Clarify QP and CQ is_kernel logic
RDMA/vmw_pvrdma: Add UAR SRQ macros in ABI header file
i40iw: Change accelerated flag to bool
After TC offloads were converted to callbacks we have no choice
but keep track of the offloaded filter in the driver.
Since this change came a little late in the release cycle
there were a number of conflicts and allocation of vNIC priv
structure seems to have slipped away in linux-next.

While in recovery process of PCI error (called EEH on PowerPC arch),
another PCI transaction could be corrupted causing a situation of
nested PCI errors. Also, this scenario could be reproduced with
error injection mechanisms (for debug purposes).
We observe that in case of nested PCI errors, bnx2x might attempt to
initialize its shmem and cause a kernel crash due to bad addresses
read from MCP. Multiple different stack traces were observed depending
on the point the second PCI error happens.
This patch avoids the crashes by:
* failing PCI recovery in case of nested errors (since multiple
PCI errors in a row are not expected to lead to a functional
adapter anyway), and by,
* preventing access to adapter FW when MCP is failed (we mark it as
failed when shmem cannot get initialized properly).

don't copy them into fifo, once MAC restart, these DMA buffers are not unmapped.
So it should check the dma mapping buffer and unmap them.

Add memory dump to the firmware crash data file which is provided to user space
via devcoredump interface. This makes it easier for firmware engineers to debug
firmware crashes.
Due to increased memory consumption the memory dump is disabled by default. To
enable it make sure that bit 3 is set in coredump_mask module parameter:
modprobe ath10k_core coredump_mask=0xffffffff
When RAMDUMP is enabled a buffer for the dump is allocated with vmalloc during
device probe. The actual memory layout is different in hardware versions and
the layouts are defined in coredump.c. The memory is split to regions and, to
get even finegrained control of what to copy, the region can split to smaller
sections as not all registers are readable (which could cause the whole system
to stall).

For memory dump support (it consumes quite a lot of memory) we need to control
what is exactly stored to the crash dump. Add a module parameter call
coredump_mask to do that. It's a bit mask of these values:
enum ath10k_fw_crash_dump_type {
ATH10K_FW_CRASH_DUMP_REGISTERS = 0,
ATH10K_FW_CRASH_DUMP_CE_DATA = 1,
ATH10K_FW_CRASH_DUMP_MAX,
};
For example, if we only want to store CE_DATA we would enable bit 2:
modprobe ath10k_core coredump_mask=0x2
