[PATCH net-next 2/5] be2net: Don't log "Out of MCCQ wrbs" error

[Sathya Perla]

From: Vasundhara Volam <vasundhara.volam@emulex.com>

Don't log "Out of MCCQ wrbs" msg. When the driver doesn't receive any
response from the FW it already logs a "FW not responding" message.
The driver runs out of MCCQ wrbs much later. Also, this message can
swamp the kernel log in HW/FW error scenarios.

[PATCH net-next 5/5] be2net: enable IOMMU pass through for be2net

[Sathya Perla]

From: Craig Hada <craig.hada@hp.com>

This patch sets the coherent DMA mask to 64-bit after the be2net driver has
been acknowledged that the system is 64-bit DMA capable. The coherent DMA
mask is examined by the Intel IOMMU driver to determine whether to allow
pass through context mapping for all devices. With this patch, the be2net
driver combined with be2net compatible hardware provides comparable
performance to the case where vt-d is disabled. The main use-case for this
change is to decrease the time necessary to copy virtual machine memory
during KVM live migration instantiations.

This patch was tested on a system that enables the IOMMU in non-coherent
mode. Two DMA remapper issues were encountered in the previous version and
both patches have been committed.

[PATCH net-next 0/5] be2net: patch-set

[Sriharsha Basavapatna]

Hi David,

The following patch set contains a few bug fixes.
Please consider applying this to the net-next tree.
Thanks.

Patch-1 Obtains proper PF number for BEx chips
Patch-2 Fixes a FW update issue seen with BEx chips
Patch-3 Updates copyright string
Patch-4 Fixes TX stats for TSO packets
Patch-5 Enables VF link state setting for BE3

******

Sriharsha Basavapatna (4):
  be2net: Provide an alternate way to read pf_num for BEx chips
  be2net: NCSI FW section should be properly updated with ethtool for
    BE3
  be2net: Update Copyright string in be_hw.h
  be2net: Fix TX stats for TSO packets

Suresh Reddy (1):
  be2net: Enable VF link state setting for BE3

Please do not target real bug fixes at net-next, they should
target 'net' instead.

And that's where I have applied this series.

Thanks.
