Add a driver that provides a character special device for each
InfiniBand port.  This device allows userspace to send and receive
MADs via write() and read() (with some control operations implemented
as ioctls).

All operations are 32/64 clean and have been tested with 32-bit
userspace running on a ppc64 kernel.

Add a driver that implements the (IPoIB) IP-over-InfiniBand protocol.
This is a network device driver of type ARPHRD_INFINIBAND (and
addr_len INFINIBAND_ALEN bytes).

The ARP/ND implementation for this driver is not completely
straightforward, because InfiniBand requires an additional path lookup
be performed (through an IB-specific mechanism) after a remote
hardware address has been resolved.  We are very open to suggestions
of a better way to handle this than the current implementation.

Although IB has a special multicast group join mode intended to
support IP multicast routing (non member join), no means to identify
different multicast styles has yet been determined, so all joins by
the driver are currently full member joins.  We are looking for
guidance in how to solve this.

The IPoIB protocol/encapsulation is described in the Internet-Drafts

Add support for handling InfiniBand MADs (management datagrams),
including sending and receiving MADs as well as passing MADs on to
local agents.

This is required for an SM (subnet manager) to discover and configure
the host, since the SM's query MADs must be passed to the local SMA
(subnet management agent).  In addition, this support is used by upper
level protocols to send queries to and receive responses from the SM.

Merry Christmas everyone. Ho ho ho!

rth tells me that some versions of gcc may end up using the
SSE registers for data movement when you do that.

Use "-march=i686 -mtune=xxxx" instead.

(We do the same thing for march=pentium2/4 too, just for
consistency).

hardware driver disconnects instead of waiting for the last user to drop off. 
This way hardware drivers can be unloaded at any time.

This fixes a build failure with gcc-3.4.1, where we use some functions
before we define them inline. 

The simple way to fix those is to simply un-inline the functions in
question. Since they are somewhat large that's what I did.

An alternative would be to rework the ordering of the file so the
functions are defined before their first use.
