Note that there still remain a couple of node type checks in the kernel
that we may want to remove. There's an IB CA check in cma.c:rdma_notify
This should check for rdma_cap_ib_cm()
as well as in rds/ib.c:rds_ib_add_one and rds_ib_laddr_check and
Not sure what the underlying reason is for

IB, RoCE, and OPA ports have the RDMA_CORE_CAP_IB_CM set so this

In an effort to reform the RDMA core and ULPs to minimize use of
node_type in struct ib_device, an additional bit is added to
struct ib_device for is_switch (IB switch). This is needed
to be initialized by any IB switch device driver. This is a
NEW requirement on such device drivers which are
