[PATCH net 0/4] Mellaox 40G driver fixes for 4.6-rc

[Or Gerlitz]

Hi Dave,

With the fix for ARM bug being under the works, these are 
few other fixes for mlx4 we have ready to go.

Eran addressed the problematic/wrong reporting of dropped packets, Daniel 
fixed some matters related to PPC EEH's and Jenny's patch makes sure
VFs can't change the port's pause settings.

Or.

[PATCH net 1/4] net/mlx4_core: Implement pci_resume callback

[Or Gerlitz]

From: Daniel Jurgens <danielj@mellanox.com>

Move resume related activities to a new pci_resume function instead of
performing them in mlx4_pci_slot_reset.  This change is needed to avoid
a hotplug during EEH recovery due to commit f2da4ccf8bd4 ("powerpc/eeh:
More relaxed hotplug criterion").

[PATCH net 2/4] net/mlx4_core: Avoid repeated calls to pci enable/disable

[Or Gerlitz]

From: Daniel Jurgens <danielj@mellanox.com>

Maintain the PCI status and provide wrappers for enabling and disabling
the PCI device.  Performing the actions more than once without doing
its opposite results in warning logs.

This occurred when EEH hotplugged the device causing a warning for
disabling an already disabled device.

[PATCH net 3/4] net/mlx4_core: Don't allow to VF change global pause settings

[Or Gerlitz]

From: Eugenia Emantayev <eugenia@mellanox.com>

Currently changing global pause settings is done via SET_PORT
command with input modifier GENERAL. This command is allowed
for each VF since MTU setting is done via the same command.

Change the above to the following scheme: before passing the
request to the FW, the PF will check whether it was issued
by a slave. If yes, don't change global pause and warn,
otherwise change to the requested value and store for
further reference.

[PATCH net 4/4] net/mlx4_en: Split SW RX dropped counter per RX ring

[Or Gerlitz]

From: Eran Ben Elisha <eranbe@mellanox.com>

Count SW packet drops per RX ring instead of a global counter. This
will allow monitoring the number of rx drops per ring.

In addition, SW rx_dropped counter was overwritten by HW rx_dropped
counter, sum both of them instead to show the accurate value.
