The mv88e6xxx.h is meant to contains the chip structures and data.
Rename it to chip.h, as for other source/header pairs of the driver.
At the same time, ensure that relative header inclusions are separated

Since commit 9b4437a5b870 ("geneve: Unify LWT and netdev handling.")
when using COLLECT_METADATA geneve devices are created with too small of
a needed_headroom and too large of a max_mtu. This is because
ip_tunnel_info_af() is not valid with the device level info when using
COLLECT_METADATA and we mistakenly fall into the IPv4 case.
For COLLECT_METADATA, always use the worst case of ipv6 since both
sockets are created.
Fixes: 9b4437a5b870 ("geneve: Unify LWT and netdev handling.")

xgbe_map_rx_buffer is rather confused about what PAGE_ALLOC_COSTLY_ORDER
means. It uses PAGE_ALLOC_COSTLY_ORDER-1 assuming that
PAGE_ALLOC_COSTLY_ORDER is the first costly order which is not the case
actually because orders larger than that are costly. And even that
applies only to sleeping allocations which is not the case here. We
simply do not perform any costly operations like reclaim or compaction
for those. Simplify the code by dropping the order calculation and use
PAGE_ALLOC_COSTLY_ORDER directly.

Use software polling (PHY_POLL) to check for link state changes instead
of relying on the EMAC's hardware polling feature. Some PHY drivers
are unable to get a functioning link because the HW polling is not
robust enough.
The EMAC is able to poll the PHY on the MDIO bus looking for link state
changes (via the Link Status bit in the Status Register at address 0x1).
When the link state changes, the EMAC triggers an interrupt and tells the
driver what the new state is. The feature eliminates the need for
software to poll the MDIO bus.
Unfortunately, this feature is incompatible with phylib, because it
ignores everything that the PHY core and PHY drivers are trying to do.
In particular:
1. It assumes a compatible register set, so PHYs with different registers
may not work.
2. It doesn't allow for hardware errata that have work-arounds implemented
in the PHY driver.
3. It doesn't support multiple register pages. If the PHY core switches
the register set to another page, the EMAC won't know the page has
changed and will still attempt to read the same PHY register.
4. It only checks the copper side of the link, not the SGMII side. Some
PHY drivers (e.g. at803x) may also check the SGMII side, and
report the link as not ready during autonegotiation if the SGMII link
is still down. Phylib then waits for another interrupt to query
the PHY again, but the EMAC won't send another interrupt because it
thinks the link is up.

If any errors are encountered while walking the device tree structure of
the MDIO bus for children, the code may silently continue, silently
exit, or throw an error and exit. This make it difficult for device
tree writers to know there is an error. Also, it makes any error in a
child entry of the MDIO bus be fatal for all entries. Instead, we
should provide verbose errors describing the error and then attempt to
continue if it all possible. Also, use of_mdio_parse_addr()

commit d85b758f72b0 ("virtio_net: fix support for small rings")
was supposed to increase the buffer size for small rings but had an
unintentional side effect of decreasing it for large rings. This seems
to break some setups - it's not yet clear why, but increasing buffer
size back to what it was before helps.

Adding a vxlan interface to a socket isn't symmetrical, while adding
is done in vxlan_open() the deletion is done in vxlan_dellink().
This can cause a use-after-free error when we close the vxlan
interface before deleting it.
We add vxlan_vs_del_dev() to match vxlan_vs_add_dev() and call
it from vxlan_stop() to match the call from vxlan_open().

40GbE Intel Wired LAN Driver Updates 2017-06-01
This series contains updates to i40e, i40evf and the "new" AVF virtchnl.
This is the introduction of the Intel(R) Ethernet Adaptive Virtual
Function driver code and device ID, as presented at the NetDEV 1.2
conference in 2016.
http://netdevconf.org/1.2/session.html?anjali-singhai
The idea is to convert the interface between the i40evf driver
and the parent i40e PF driver to be generic, as the i40evf driver
should in the future be able to run on top of other Intel PF
drivers, and negotiate any features beyond a "base expected" set.
