[ofw] ConnectX driver code

It is not a must to build everything using one compiler, but it makes
life much easier.

I agree that after you build one component using the new compiler, and
have tested it thoroughly, you don't need the old compiler any more.
Throwing away the old compiler after you only started working with the
new compiler is not that good idea. Once you will find some race, you
will always stay with the doubt that the problem is in the compiler.

Two more notes:
1) We can probably continue for the moment with the old compiler, but we
will have to move on sooner or later.
2) The real reason that it takes such a long time to move between the
old compiler and the new compiler is not really related to the new
compiler.
The main reason is there are 3 modes that we want to support: 1)  64
windows. 2)  32 bits windows and 3) 32 bits application working over 64
bit windows. The real problem is making 3 work with the new compiler. As
far as we see it now it never really worked with the old compiler as
well. So I believe the time that it takes now is really a bug fix rather
than a move to a new compiler.
 
Thanks
Tzachi
