RDMA/core: Add support for the new ARPHRD_UB

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8AL44



--------------------------------------------------------------------------

For RDMA over UB Link mode, UB Link replaces the current Ethernet.
Add a new ARP protocol HW ID 38 and enable CM link building and
netdevice event for this mode.
