Part of the old remote management feature is a piece of code
that checked permissions on the local system to see if a certain
operation was permitted, and if so pass the command to a remote

with commit 5902385a ("tipc: obsolete the remote management

that GPHY major revision is in bits 15:12, minor in bits 11:8 and patch

Introduce a small heuristic which checks for the old scheme first, tests
for the new scheme and finally attempts to catch reserved values and

This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.

It modifies drivers implementation of set/get_rxfh accordingly.

This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.

User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.

Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

Intel Wired LAN Driver Updates 2014-12-06

This series contains updates to i40e and i40evf.

Shannon provides several patches to cleanup and fix i40e.  First removes
an unneeded break statement in i40e_vsi_link_event().  Then removes
some debug messages that really do not give any useful information and
ends up getting printed every service_task loop, which fills the logfile
with noise when AQ tracing is enabled.  Updates the aq_cmd arguments to
use %i which is much more forgiving and user friendly than the more
restrictive %x, or %d.  Fixes the netdev_stat macro, where the old
xxx_NETDEV_STAT() macro was defined long before the newer
rtnl_link_stats64 came into being, and just never got updated.
Getting the pf_id from the function number had an issue when
when the PF was setup in passthru mode, the PCI bus/device/function
was virtualized and the number in the VM is different from the number in
the bare metal.  This caused HW configuration issues when the wrong pf_id
was used to set up the HMC and other structures.  The PF_FUNC_RID register
has the real bus/device/function information as configured by the BIOS,
so use that for a better number.

Carolyn adds additional text description for the base pf0 and flow
director generated interrupts, since these interrupts are difficult
to distinguish per port on a multi-function device.

Jacob resolves an issue related to images with multiple PFs per
physical port.  We cannot fully support 1588 PTP features, since only
one port should control (i.e. write) the registers at a time.  Doing
so can cause interference of functionality.

Anjali provides several updates to i40e, first adds the Virtual Channel
OP event opcode for CONFIG_RSS, so that the Virtual Channel state
machine can properly decipher status change events.  Then updates the
driver to add (and use) i40e_is_vf macro for future expansion when new
VF MAC types get added.  Adds new update VSI flow to accommodate a
firmware dix with VSI loopback mode.  All VSIs on a VEB should either
have loopback enabled or disabled, a mixed mode is not supported for a
VEB.  Since our driver supports multiple VSIs per PF that need to talk to
each other make sure to enable Loopback for the PF and FDIR VSI as well.

Mitch provides a couple of i40e and i40evf patches.  First updates
i40evf init code more adept at handling when multiple VFs attempt
to initialize simultaneously.

Joe Perches provides a i40e patch which resolves a compile warning
about about frame size being larger than 2048 bytes by reducing the
stack use by using kmemdup and not using a very large struct on the
stack.

v2:
 - Dropped patch 13 & 14 while Mitch reworks the patches based on
   feedback from Ben Hutchings, probably the tryptophan in the turkey
   is to blame for the delay...
 - Added Joe Perches patch which resolves a compile warning about frame
   size

net: Add helper for padding short Ethernet frames

This patch series adds a pair of helpers to pad short Ethernet frames.  The
general idea is to clean up a number of code paths that were all writing
their own versions of the same or similar function.

An added advantage is that this will help to discourage introducing new
bugs as in at least one case I found the skb->len had been updated, but the
tail pointer update was overlooked.

v2: Added skb_put_padto for cases where length is not ETH_ZLEN

Update the Intel Ethernet drivers to use eth_skb_pad() and skb_put_padto
instead of doing their own implementations of the function.

Also this cleans up two other spots where skb_pad was called but the length
and tail pointers were being manipulated directly instead of just having
the padding length added via __skb_put.

This patch adds two new helper functions skb_put_padto and eth_skb_pad.
These functions deviate from the standard skb_pad or skb_padto in that they
will also update the length and tail pointers so that they reflect the
padding added to the frame.

The eth_skb_pad helper is meant to be used with Ethernet devices to update
either Rx or Tx frames so that they report the correct size.  The
skb_put_padto helper is meant to be used primarily in the transmit path for
network devices that need frames to be padded up to some minimum size and
don't wish to simply update the length somewhere external to the frame.

The motivation behind this is that there are a number of implementations
throughout the network device drivers that are all doing the same thing,
but each a little bit differently and as a result several implementations
contain bugs such as updating the length without updating the tail offset
and other similar issues.
