Adds support to set filters with multiple header fields (L3,L4)to match on.
This is achieved in the following order:
1. Create a leaf hash table for the next header.
2. Create a link to the leaf hash table from the base hash table with
   matches on next header type and current header fields.
3. Add filter in leaf hash table with match on next header fields and
   action.

Verified with the following filters :

Match TCP and DIP:
        handle 1: u32 divisor 1
        u32 ht 800: order 1 link 1: \
        offset at 0 mask 0f00 shift 6 plus 0 eat \
        match ip protocol 6 ff match ip dst 10.0.0.1/32
        match tcp src 28 ffff action drop

Delete the filter:

Match on DIP, SIP, UDP (SPort, DPort):
        handle 2: u32 divisor 1
        u32 ht 800: order 2 link 2: \
        offset at 0 mask 0f00 shift 6 plus 0 eat \
        match ip dst 15.0.0.2/32 match ip protocol 17 ff \
        match ip src 15.0.0.1/32

Since commit b74766a0 ("phylib: don't return NULL
from get_phy_device()") in linux-next, phy_get_device() will return
ERR_PTR(-ENODEV) instead of NULL if the PHY device ID is all ones.

This causes problem with stmmac driver and likely some other drivers
which call mdiobus_register(). I triggered this bug on SoCFPGA MCVEVK
board with linux-next 20160427 and 20160428. In case of the stmmac, if
there is no PHY node specified in the DT for the stmmac block, the stmmac
driver ( drivers/net/ethernet/stmicro/stmmac/stmmac_mdio.c function
stmmac_mdio_register() ) will call mdiobus_register() , which will
register the MDIO bus and probe for the PHY.

The mdiobus_register() resp. __mdiobus_register() iterates over all of
the addresses on the MDIO bus and calls mdiobus_scan() for each of them,
which invokes get_phy_device(). Before the aforementioned patch, the
mdiobus_scan() would return NULL if no PHY was found on a given address
and mdiobus_register() would continue and try the next PHY address. Now,
mdiobus_scan() returns ERR_PTR(-ENODEV), which is caught by the
'if (IS_ERR(phydev))' condition and the loop exits immediately if the
PHY address does not contain PHY.

Repair this by explicitly checking for the ERR_PTR(-ENODEV) and if this
error comes around, continue with the next PHY address.

This patch makes it so that i40e and i40evf can use GSO_PARTIAL to support
segmentation for frames with checksums enabled in outer headers.  As a
result we can now send data over these types of tunnels at over 20Gb/s
versus the 12Gb/s that was previously possible on my system.

The advantage with the i40e parts is that this offload is mostly
transparent as the hardware still deals with the inner and/or outer IPv4
headers so the IP ID is still incrementing for both when this offload is
performed.
