UNIC: add support for tc speed limitation 

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I850RQ


CVE: NA

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

In UB mode, support for 5 TC is required, while alse needing support for
TC-level rate limiting to differentiate between services.

This patch adds support for UB on the basis of originally only supporting
TC speed limit in ROH mode.
