This is done as a preparation before introducing support for neighbor

until now it was used only by mgpc and thus it was private. This patch
updates the namespace for more generic usage.

Up until now the dpipe table's size was static and known at registration
time. The host table does not have constant size and it is resized in
dynamic manner. In order to support this behavior the size is changed
to be obtained dynamically via an op.

This patch also adjust the current dpipe table for the new API.

In the NIC firmware, the 1-bit flag indicating "firmware is loaded" moved
from SLI_SCRATCH_1 to SLI_SCRATCH_2 (these are Octeon general-purpose
scratch registers).  Make the PF driver conform to this change.

Remove code that sets the "firmware is loaded" flag because it's now the
firmware's job to do that.

In the code that detects whether or not the firmware is loaded, don't just
rely on checking the "firmware is loaded" flag because that may cause a
rare false negative.  Add code that deduces whether or not the firmware is
loaded; that will never give a false negative.

Also bump up driver version to match newer NIC firmware.

The patch add the functions to switch UDP hash level between
L3 and L4 by ethtool command. UDP over IPv4 and v6 can be set
differently. The default hash level is L4. We currently only
allow switching TX hash level from within the guests.

On Azure, fragmented UDP packets have high loss rate with L4
hashing. Using L3 hashing is recommended in this case.

For example, for UDP over IPv4 on eth0:
To include UDP port numbers in hasing:
	ethtool -N eth0 rx-flow-hash udp4 sdfn
To exclude UDP port numbers in hasing:
	ethtool -N eth0 rx-flow-hash udp4 sd
To show UDP hash level:
	ethtool -n eth0 rx-flow-hash udp4
