If the local representation of the global TT table of one originator has
more VLAN entries than the respective TT update, there is some
inconsistency present. By detecting and reporting this inconsistency,
the global table gets updated and the excess VLAN will get removed in
the process.

With device tree it is no more possible to reset the PHY at board
level. Furthermore, doing in the driver allow to power down the PHY when
the network interface is no more used.

This reset can't be done at the PHY driver level. The PHY must be able to
answer the to the mii bus scan to let the kernel creating a PHY device.

The patch introduces a new optional property "phy-reset-gpios" inspired
from the one use for the FEC.

When sending skbs, qeth determines the number of qdio SBAL elements
required. If qeth sends a fragmented skb, the SBAL element number
calculation is wrong, because the fragmented data part is added
twice in qeth_l3_tso_elements(). This patch makes sure fragmented
data is handled in qeth_elements_for_frags() only, while
qeth_l3_tso_elements() starts calculation of qdio SBAL elements just
with the linear data part of the skb.

This patch removes ARPHRD_IEEE802154 from addrconf handling. In the
earlier days of 802.15.4 6LoWPAN, the interface type was ARPHRD_IEEE802154
which introduced several issues, because 802.15.4 interfaces used the
same type.

Since commit 965e613d ("ieee802154: 6lowpan: fix ARPHRD to
ARPHRD_6LOWPAN") we use ARPHRD_6LOWPAN for 6LoWPAN interfaces. This
patch will remove ARPHRD_IEEE802154 which is currently deadcode, because
ARPHRD_IEEE802154 doesn't reach the minimum 1280 MTU of IPv6.

Also we use 6LoWPAN EUI64 specific defines instead using link-layer
constanst from 802.15.4 link-layer header.

100GbE Intel Wired LAN Driver Updates 2015-12-13

This series contains updates to fm10k only.

Jacob updates the driver to use ether_addr_copy() instead of copying
byte-by-byte in a for loop.  Fixed up CamelCase variable names and coding
style issues.  Cleaned up namespace pollution of fm10k_iov_msg_data_pf().
Cleaned up, by making it consistent, the use of VLAN and VLAN ID instead of
vlan or vid.  Lastly, update the driver to initialize XPS so that we can
take advantage of the kernel feature.

Alex Duyck fixed up the driver to free the resources associated with the
MSI-X vector table if the q_vector allocation failed.  Then fixed the driver
to check for msix_entries to be NULL and freed the IRQ if the mailbox API
returned an error on trying to connect.

Bruce cleans up whitespace and namespace pollution issues in the driver.
Also updates the driver to use the BIT() macro instead of bit-shifting coding.

First is the fact that the fm10k_mbx_free_irq was assuming msix_entries was
