RDMA/hns: Pass mac type to user driver for ROH mode 

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5WKYW



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

The user mode driver needs to use the mac type to sense whether
it is in ROH mode, so it is necessary to add the mac type to
the user mode driver.
