The driver was allowing the user to set larger size MTU
than the hardware was being configured to support.
The driver was already using VLAN_HLEN when setting the
hardware max receivable frame size, so just add it to the
netdev MTU set entry point as well.

Register range, being subject to register diagnostic, can vary among
different NVMs. We will try to identify the full range and use it for
a register test. This is needed to avoid false test results. If we fail
to define the proper register range we will test only the first register
from that group.

Since v2.4 the capi driver used the following device nodes if
"middleware" support was enabled:
/dev/capi20
/dev/capi/0
/dev/capi/1
[...]
/dev/capi20 is a character device node. /dev/capi/0 (and up) are tty
device nodes (with a different major).
This device node (naming) scheme is not documented anywhere, as far as I
know. It was originally provided by the capifs pseudo filesystem (before
udev became available). It is required for example by the pppd
capiplugin. It was supported until a few years ago. But a number of
developments broke it:
- v2.6.6 (May 2004) renamed /dev/capi20 to /dev/capi and removed the
"/" from the name of capi's tty driver. The explanation of the patch
that did this included two examples of udev rules "to restore the old
namespace";
- either udev 154 (May 2010) or udev 179 (January 2012) stopped
allowing to rename device nodes, and thus the ability to have
/dev/capi20 appear instead of /dev/capi and /dev/capi/0 (and up)
instead of /dev/capi0 (and up);
- v3.0 (July 2011) also removed capifs. That disabled another method to
create the /dev/capi/0 (and up) device nodes.
So now users need to manually tweak their setup (eg, create /dev/capi/
and fill that with symlinks) to get things working. This is all rather
hacky and only discoverable by searching the web. Fix all this by
renaming /dev/capi back to /dev/capi20, and by setting the name of the
"capi_nc" tty driver to "capi!" so the tty device nodes appear as
/dev/capi/0 (and up).

The Kconfig symbol ISDN_DRV_AVMB1_VERBOSE_REASON is only used for
capi_info2str(). That function is only used in capidrv.c. So setting it
without setting ISDN_CAPI_CAPIDRV is pointless. Make it depend on
ISDN_CAPI_CAPIDRV, rename it to ISDN_CAPI_CAPIDRV_VERBOSE and put its
entry after ISDN_CAPI_CAPIDRV's entry.
Since this symbol seems to be primarily used for debugging, keep it off
by default. By now the last users of capidrv hopefully know all they
need to know about the reasons for disconnecting.

To make TLB mode work, the patch allows learning packets
to be sent using mac addresses assigned to macvlan devices,
also taking into an account vlans that may be between the
bond and macvlan device.
To make RLB work, all we have to do is accept ARP packets
for addresses added to the bond dev->uc list. Since RLB
mode will take care to update the peers directly with
correct mac addresses, learning packets for these addresses
do not have be send to switch.

Bonding and team drivers generate specific events during failover
that trigger switch updates. When a macvlan device is configured
on top of bonding, we want switches to learn about the macvlan
devices as well. This patch adds a handler to macvlan driver to
propagate these events to all macvlan devices. We let the generic
inetdev event handler do the work.
This allows macvlan to operated correctly over active-backup
mode bond.

Bonding devices manage the unicast filters of the underlying
interfaces, but do not turn on IFF_UNICAST_FLT flag. Thus
anytime a unicast address is added to the bond, the bond is
places in promiscuous mode.
Turn on IFF_UNICAST_FLT on the bond device so that the bond does
not go into promiscuous mode needlesly. If an underlying device
does not support unicast filtering, that device will automaticall
enter promiscuous mode already.

====================
Intel Wired LAN Driver Updates
This series contains updates to e1000, igb and ixgbe.
Emil provides his version 2 fix for the detection of SFP+ capable interfaces.
In cases where the driver is loaded while there are no SFP+ modules in cage,
the interface was not being detected as SFP capable. Resolve the issue by
identifying interfaces with no PHY type set as SFP capable which allows the
driver to detect the SFP module when the interface is brought up. In this
version 2 of the patch, the 82599 specific check was removed since we only
have 82598 devices that are SFP capable.
Jacob removes the including of the export header in the ixgbe PTP core, since
it is not needed. Renames igb_ptp_enable() to igb_ptp_feature_enable() to
better reflect the actual functions purpose.
Todd fixes the ethtool loopback test for i354 backplane devices since we
do not know what PHY is to be used for the devices, use MAC loopback for
ethtool tests. Todd also sets the packet buffer size register defaults for
i210 devices.
Yongjian Xu removes the check for skb->len being negative or zero since there
is never a case where it would be zero or negative for e1000.
Manuel Schölling updates e1000 to use the time_after() helper function.

In cases where the driver is loaded while there are no SFP+ modules in
the cage the interface was not being detected as SFP capable. To account
for this the driver called identify_sfp in ixgbe_get_settings to make
sure the data is correct. However when there is no SFP+ module in the cage
the driver waits for the I2C reads to time out which can take more than a
second and will cause issues with tools (like net-snmp) that may poll
for that information.
This patch resolves the issue by identifying interfaces with no PHY
type set as SFP capable which allows the driver to detect the SFP module
when the interface is brought up. As result of this we can also remove the
identify_sfp call from ixgbe_get_settings.
v2: remove the 82599 specific check since we have 82598 devices that are SFP
capable.

The current behaviour of the sh_eth driver is not to use the RNC bit
for the receive ring. This means that every packet recieved is not only
generating an IRQ but it also stops the receive ring DMA as well until
the driver re-enables it after unloading the packet.
This means that a number of the following errors are generated due to
the receive packet FIFO overflowing due to nowhere to put packets:
net eth0: Receive FIFO Overflow
Since feedback from Yoshihiro Shimoda shows that every supported LSI
for this driver should have the bit enabled it seems the best way is
to remove the RMCR default value from the per-system data and just
write it when initialising the RMCR value. This is discussed in
the message (http://www.spinics.net/lists/netdev/msg284912.html).
I have tested the RMCR_RNC configuration with NFS root filesystem and
the driver has not failed yet. There are further test reports from
Sergei Shtylov and others for both the R8A7790 and R8A7791.
There is also feedback fron Cao Minh Hiep[1] which reports the
same issue in (http://comments.gmane.org/gmane.linux.network/316285)
showing this fixes issues with losing UDP datagrams under iperf.

"Two md bugfixes for possible corruption when restarting reshape
If a raid5/6 reshape is restarted (After stopping and re-assembling
the array) and the array is marked read-only (or read-auto), then the
reshape will appear to complete immediately, without actually moving
anything around. This can result in corruption.
There are two patches which do much the same thing in different
places. They are separate because one is an older bug and so can be
applied to more -stable kernels"
* tag 'md/3.15-fixes' of git://neil.brown.name/md:
md: always set MD_RECOVERY_INTR when interrupting a reshape thread.
md: always set MD_RECOVERY_INTR when aborting a reshape or other "resync".

The ec_bhf driver is specific to the Beckhoff CX embedded PC series.
These are based on Intel x86 CPU. So we can add a dependency on
X86, with COMPILE_TEST as an alternative to still allow for broader
build-testing.

Instead of using a jiffies hack we can use the standard api for delays.
