This patch moves ocrdma vendor's specific structures to
common UAPI folder which will be visible to all consumers.

These structures are used by user-space library driver
(libmlx4) and currently manually copied to that library.

This move will allow cross-compile against these files and
simplify introduction of vendor specific data.

In addition, it changes types to be __uXX instead of uXX.

This is done in two steps:
1) Issuing CREATE_VPORT_LAG in order to have Ethernet traffic from
both ports arriving on PF0 root flowtable, so we will be able to catch
all raw-eth traffic on PF0.
2) Creation of LAG demux flowtable in order to direct all non-raw-eth
traffic back to its source port, assuring that normal Ethernet
traffic "jumps" to the root flowtable of its RX port (non-LAG behavior).

Since ib_query_port() in RoCE returns the state of its netdev as the port
state, it makes sense to propagate the port up/down events to ib_core
when the netdev port state changes, instead of relying on traditional
core events.

This also keeps both the event and ib_query_port() synchronized.

Flow steering specifications structures were implemented as in an
extensible way that allows one to add new filters and new fields
to existing filters.
These specifications have never been extended, therefore the
kernel flow specifications size and the user flow specifications size
were must to be equal.

In downstream patch, the IPv4 flow specifications type is extended to
support TOS and TTL fields.

To support an extension we change the flow specifications size
condition test to be as following:

* If the user flow specifications is bigger than the kernel
specifications, we verify that all the bits which not in the kernel
specifications are zeros and the flow is added only with the kernel
specifications fields.

* Otherwise, we add flow rule only with the user specifications fields.

User space filters must be aligned with 32bits.
