Yes, as Roland commented in the past, every IB driver has two souls... 
for example IPoIB is a network driver and IB driver, SRP is a SCSI LLD 
and IB driver, iSER is an IB driver, a SCSI LLD and an iSCSI trasport 
provider, etc etc. The point is that IB/RDMA is special enough for it to 
have its own code location and maintainer in the mainline kernel.

RDS is a socket provider and if this socket has also implementation over 
tcp/stream sockets it sounds like its --core-- code belong to the net 
section of the code base.

no. For example iscs/tcp uses TCP sockets and is under drivers/scsi
