Re: [net-next v5 0/8] dpaa_eth: Add the Freescale DPAA Ethernet driver

Hi Timur,

I've managed somehow to make got send-email to move the From: line in the body 
instead of the header, probably typed something wrong when asked to confirm the 
sender. I've resent the series.

Regards,
Madalin

Please fix your git-send-email configuration, so that your emails are

[net-next v5 0/8] dpaa_eth: Add the Freescale DPAA Ethernet driver

2015-12-04 Thread linuxppc-dev-bounces+archive=mail-archive . com 
From: Madalin Bucur 

This patch series adds the Ethernet driver for the Freescale
QorIQ Data Path Acceleration Architecture (DPAA).

This version includes changes following the feedback received
on previous versions from Eric Dumazet, Bob Cochran, Joe Perches,
Paul Bolle, Joakim Tjernlund, Scott Wood, David Miller - thank you.

Together with the driver a managed version of alloc_percpu
is provided that simplifies the release of per-CPU memory.

The Freescale DPAA architecture consists in a series of hardware
blocks that support the Ethernet connectivity. The Ethernet driver
depends upon the following drivers that are currently in the Linux
kernel or in review (the underlying drivers are not inter-dependent):
 - Peripheral Access Memory Unit (PAMU)
drivers/iommu/fsl_*
 - Frame Manager (FMan)
drivers/net/ethernet/freescale/fman
 - Queue Manager (QMan), Buffer Manager (BMan)
drivers/soc/fsl/qbman

dpaa_eth interfaces mapping to FMan MACs:

  dpaa_eth   /eth0\ ...   /ethN\

The latest Q/BMan drivers were submitted by Roy Pledge:
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?submitter=66331=*

Changes from v4:
 - addressed feedback from Scott Wood and Joe Perches
 - fixed spelling
 - fixed leak of uninitialized stack to userspace
 - fix prints
 - replace raw_cpu_ptr() with this_cpu_ptr()
 - remove _s from the end of structure names
 - remove underscores at start of functions, goto labels
 - remove likely in error paths
 - use container_of() instead of open casts
 - remove priv from the driver name
 - move return type on same line with function name
 - drop DPA_READ_SKB_PTR/DPA_WRITE_SKB_PTR

Changes from v3:
 - removed bogus delay and comment in .ndo_stop implementation
 - addressed minor issues reported by David Miller

Changes from v2:
 - removed debugfs, moved exports to ethtool statistics
 - removed congestion groups Kconfig params

Changes from v1:
 - bpool level Kconfig options removed
 - print format using pr_fmt, cleaned up prints
 - __hot/__cold removed
 - gratuitous unlikely() removed
 - code style aligned, consistent spacing for declarations
 - comment formatting

There is one u-boot patch that one needs to make sure it's applied
to align u-boot to the latest device tree binding document specification
used by the FMan driver. Please make sure your u-boot includes this patch:
