Dump some internal state about VFs through debugfs. This provides
information not available with 'ip link show'. To use, write "dump vf
<id>" to the command file, or just "dump vf" to dump information on all
of the VFs.

This patch fixes an issue I introduced when I converted the code over to
using the length field to determine if a descriptor was done or not. It
turns out that we are also processing programming descriptors in the Rx
path and need to have these processed even though the length field will be
0 on these packets. What will happen with a programming descriptor is that
we will receive a descriptor that has the SPH bit set, and the header
length and packet length fields cleared.
To account for this we should be checking for the bit for split header
being set even though we aren't actually using header split. This bit is
set in the length field to indicate if a programming descriptor response is
contained in the descriptor. Since we don't support header split we don't
need to perform the extra checks of using a fixed value for the entire
length field.
In addition I am moving the function for checking if a filter is a
programming status filter into the i40e_txrx.c file since there is no
longer support for FCoE it doesn't make sense to keep this file in i40e.h.

Rx checksum offload for tunneled packets was never being negotiated or
requested by VF. This capability was assumed by default and enabled in
current hardware for VF. Going forward, this feature needs to be disabled
or advanced ptypes should be negotiated with PF in the future.

We disable VxLAN offload when more than 1 UDP port is added to the driver,
since Skyhawk doesn't support offload with multiple ports. The existing
driver design expects the user to delete all port configurations and create
a configuration with a single UDP port for VxLAN offload to be re-enabled.
Remove this restriction by tracking the ports added and re-enabling offload
when ports get deleted and only 1 port is left.

This patch adds extended statistics reporting to ethtool.
In summary, this patch,
- adds ethtool.h with the statistics register definitions
- adds 'struct xge_gstrings_extd_stats' to gather extended stats
- modifies xge_get_strings(), get_sset_count() and
get_ethtool_stats() accordingly
- moves 'struct xge_gstrings_stats' to ethtool.h

We need to ensure the loads from the descriptor are done after the
MMIO store clearing the interrupts has completed, otherwise we
might still miss work.
A read back from the MMIO register will "push" the posted store and
ioread32 has a barrier on weakly aordered architectures that will
order subsequent accesses.

Bonding driver changes the skb->dev to the bonding-master before
passing the packet to stack for further processing. This, however
does not make sense for the link-local packets and it loses "the
link info" once its skb->dev is changed to bonding-master. This
patch changes this behavior for link-local packets by not changing
the skb->dev to the bonding-master and maintaining it as it is,
i.e. the link on which the packet arrived.

kernel.
- Many fixes to 6LoWPAN, in particular for BLE
- New CA8210 IEEE 802.15.4 device driver (accounting for most of the
lines of code added in this pull request)
- Added Nokia Bluetooth (UART) HCI driver
- Some serdev & TTY changes that are dependencies for the Nokia
driver (with acks from relevant maintainers and an agreement that
these come through the bluetooth tree)
- Support for new Intel Bluetooth device
- Various other minor cleanups/fixes here and there
Please let me know if there are any issues pulling. Thanks.

Recently, suspend/resume and WOL support are added into mvneta driver.
If we enable WOL, then we get some error as below on Marvell BG4CT
platforms during suspend:
[ 184.149723] dpm_run_callback(): mdio_bus_suspend+0x0/0x50 returns -16
[ 184.149727] PM: Device f7b62004.mdio-mi:00 failed to suspend: error -16
-16 means -EBUSY, phy_suspend() will return -EBUSY if it finds the
device has WOL enabled.
We fix this issue by properly setting the netdev's power.can_wakeup
and power.wakeup, i.e
1. in mvneta_mdio_probe(), call device_set_wakeup_capable() to set
power.can_wakeup if the phy support WOL.
2. in mvneta_ethtool_set_wol(), call device_set_wakeup_enable() to
set power.wakeup if WOL has been successfully enabled in phy.

phylib has some undesirable behaviour when forcing a link mode through
ethtool. phylib uses this code:
idx = phy_find_valid(phy_find_setting(phydev->speed, phydev->duplex),
features);
to find an index in the settings table. phy_find_setting() starts at
index 0, and scans upwards looking for an exact speed and duplex match.
When it doesn't find it, it returns MAX_NUM_SETTINGS - 1, which is
10baseT-Half duplex.
phy_find_valid() then scans from the point (and effectively only checks
one entry) before bailing out, returning MAX_NUM_SETTINGS - 1.
phy_sanitize_settings() then sets ->speed to SPEED_10 and ->duplex to
DUPLEX_HALF whether or not 10baseT-Half is supported or not. This goes
against all the comments against these functions, and 10baseT-Half may
not even be supported by the hardware.
Rework these functions, introducing a new method of scanning the table.
There are two modes of lookup that phylib wants: exact, and inexact.
- in exact mode, we return either an exact match or failure
- in inexact mode, we return an exact match if it exists, a match at
the highest speed that is not greater than the requested speed
(ignoring duplex), or failing that, the lowest supported speed, or
failure.
The biggest difference is that we always check whether the entry is
supported before further consideration, so all unsupported entries are
not considered as candidates.
This results in arguably saner behaviour, better matches the comments,
and is probably what users would expect.
This becomes important as ethernet speeds increase, PHYs exist which do
not support the 10Mbit speeds, and half-duplex is likely to become
obsolete - it's already not even an option on 10Gbit and faster links.
