IPv6 GRO over GRE tap is not working while GRO is not set
over the native interface.
gro_list_prepare function updates the same_flow variable
of existing sessions to 1 if their mac headers match the one
of the incoming packet.
same_flow is used to filter out non-matching sessions and keep
potential ones for aggregation.
The number of bytes to compare should be the number of bytes
in the mac headers. In gro_list_prepare this number is set to
be skb->dev->hard_header_len. For GRE interfaces this hard_header_len
should be as it is set in the initialization process (when GRE is
created), it should not be overridden. But currently it is being overridden
by the value that is actually supposed to represent the needed_headroom.
Therefore, the number of bytes compared in order to decide whether the
the mac headers are the same is greater than the length of the headers.
As it's documented in netdevice.h, hard_header_len is the maximum
hardware header length, and needed_headroom is the extra headroom
the hardware may need.
hard_header_len is basically all the bytes received by the physical
till layer 3 header of the packet received by the interface.
For example, if the interface is a GRE tap then the needed_headroom
should be the total length of the following headers:
IP header of the physical, GRE header, mac header of GRE.
It is often used to calculate the MTU of the created interface.
This patch removes the override of the hard_header_len, and
assigns the calculated value to needed_headroom.
This way, the comparison in gro_list_prepare is really of
the mac headers, and if the packets have the same mac headers
the same_flow will be set to 1.

The main motive of this patch is to lay down driver's
tc offload infrastructure in place.
With these changes tc can offload various supported flow

action. Dropped flows statistic is a global counter for
all the offloaded flows for drop action and is populated
in ethtool statistics as common "gft_filter_drop".
Examples -
tc qdisc add dev p4p1 ingress
tc filter add dev p4p1 protocol ipv4 parent ffff: flower \

Add support for XGMAC2 in stmmac
This series adds support for 10Gigabit IP in stmmac. The IP is called XGMAC2
and has many similarities with GMAC4. Due to this, its relatively easy to
incorporate this new IP into stmmac driver by adding a new block and
filling the necessary callbacks.
The functionality added by this series is still reduced but its only a
starting point which will later be expanded.
I splitted the patches into funcionality and to ease the review. Only the
patch 8/9 really enables the XGMAC2 block by adding a new compatible string.
Version 4 addresses review comments of Florian Fainelli and Rob Herring.
NOTE: Although the IP supports 10G, for now it was only possible to test it
at 1G speed due to 10G PHY HW shipping problems. Here follows iperf3

More complete PHYLINK support for mv88e6xxx
Previous patches added sufficient PHYLINK support to the mv88e6xxx
that it did not break existing use cases, basically fixed-link phys.
This patchset builds out the support so that SFP modules, up to
2.5Gbps can be supported, on mv88e6390X, on ports 9 and 10. It also
provides a framework which can be extended to support SFPs on ports
2-8 of mv88e6390X, 10Gbps PHYs, and SFP support on the 6352 family.
Russell King did much of the initial work, implementing the validate
and mac_link_state calls. However, there is an important TODO in the
commit message:
needs to call phylink_mac_change() when the port link comes up/goes down.
The remaining patches implement this, by adding more support for the
SERDES interfaces, in particular, interrupt support so we get notified
when the SERDES gains/looses sync.
This has been tested on the ZII devel C, using a Clearfog as peer
device.
