391df37829 ramips: mt7620: add EPHY base mdio address changing possibility
In some boards is requred to change the ephy mdio base address.

This patch add of property "mediatek,ephy-base-address" in gsw
part, which allows to change ephy base address.

c02a9a2514 ramips: mt7620: fix external PHY autopolling
The port initialisation is based on assumption that phy address and
port number is the same. SoC allow different numbers and some board
have it.

Use phy address instead the port number to make sure that correct
addresses are polled.

In situation when only one PHY with address 0x0 is conected to
port 4, autopolling is broken.

This patch make autopolling correct when port number and phy address
are different.

f96c7f697f ramips: handle mdio address and switch port seperate
The phy handling code forces a phy mdio address and the switch port to
which a phy is attached to be the same. Albeit such a configuration is
used for most boards, it isn't for all.

Pass the switch port number to the ethernet phy connect functions, to
ensure the correct list entry is edited and not the list entry that
matches th phys mdio address.

Use the mdio address with mdiobus_get_phy instead of the port number,
to make sure the expected ethernet phy gets connected.

fb423f6e01 ramips: ignore already handled ethernet phys
The whole logic in fe_phy_connect() is based on the asumption that mdio
address and switch port id are equal. Albeit it is true for most
boards, it doesn't is for all.

It isn't yet clear which subtargets/boards require the devicetree less
ethernet phy handling. Hence change the code in a way that it doesn't
touch ethernet phys which were early attached and are already handled.

fe7d965ea9 ramips: fix two-way hash and auto ageout on MT7621
Current code directly writes the FOE entry to hash_val+1 position
when hash collision occurs. However, it is found that this behavior
will cause the cache and the hardware FOE table to be inconsistent.

For example, there are three flows, and their hashed values are all
equal to 100. The first flow is written to the position of 100. The
second flow is written to the position of 100+1. Then, the logic of
the current code will also write the third flow to 100+1.

At this time, the cache has flow 1 and 2; and the hardware FOE table
has flow 1 and 3, where these two parts store different contents.
So it is necessary to check whether the hash_val+1 is also occupied
before writing. If hash_val+1 is also occupied, we won’t bind th
third flow to the FOE table.

Addition to that, we also cancel the processing of foe_entry removal
because the hardware has auto age-out ability. The hardware will
periodically iterate through the FOE table to find out the time-out
entry and set it as INVALID.

6b9bdbd493 ramips: add two-way hashing scheme for MT7621
Sometimes the tuples might be hashed to the same FOE entry.
When this hash collision problem occurs, some of the
connections will not be bound and consequently the CPU
idle rate cannot reach 100%. Therefore, two-way hashing
is adopted to alleviate this problem.

f6d81e2fa1 mt7620: gsw: make IntPHY and ExtPHY share mdio addr 4 possible
To share mdio addr for IntPHY and ExtPHY,
as described in the documentation (MT7620_ProgrammingGuide.pdf).
(refer: http://download.villagetelco.org/hardware/MT7620/MT7620_ProgrammingGuide.pdf)

when port4 setup to work as gmac mode, dts like:

&gsw {
    mediatek,port4 = "gmac";
};

we should set SYSCFG1.GE2_MODE==0x0 (RGMII).
but SYSCFG1.GE2_MODE may have been set to 3(RJ-45) by uboot/default
so we need to re-set it to 0x0

before this changes:
gsw: 4FE + 2GE may not work correctly and MDIO addr 4 cannot be used by ExtPHY

after this changes:
gsw: 4FE + 2GE works and MDIO addr 4 can be used by ExtPHY

379fe50672 ramips: fix gigabit switch PHY access on MDIO
When PHY's are defined on the MDIO bus in the DTS, gigabit support was
being masked out for no apparent reason, pegging all such ports to 10/100.
If gigabit support must be disabled for some reason, there should be a
"max-speed" property in the DTS.

5a6229a93d ramips: remove superfluous & confusing DT binding
Mediatek has a reference platform that pairs an MT7620A with an MT7530W,
where the latter responds on MDIO address 0x1f while both chips respond on
0x0 to 0x4. The driver special-cases this arrangement to make sure it's
talking to the right chip, but two different ways in two different places.
This patch consolidates the detection without the current requirement of
both tests to be separately satisfied in the DTS.

0c285bd081 ramips: ethernet: use own page_frag_cache
Using the NAPI or netdev frag cache along with other drivers can lead to
32 KiB pages being held for a long time, despite only being used for
very few page fragment.
This can happen if the ethernet driver grabs one or two fragments for rx
ring refill, while other drivers use (and free up) the remaining
fragments. The 32 KiB higher-order page can only be freed once all users
have freed their fragments, which only happens after the rings of all
drivers holding the fragments have wrapped around.

Depending on the traffic patterns, this can waste a lot of memory and
look a lot like a memory leak

9a4253b81f ramips: improve ethernet driver performance with GRO/TSO
GRO stores packets as fraglist. If they are routed back to the ethernet
device, they need to be re-segmented if the driver does not support
sending fraglists.
Add the missing support for that, along with a missing feature flag that
allows full routed GRO->TSO offload.
Considerably reduces CPU utilization for routing
