net: hns3: add support for vf get dscp configuration from pf 

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


CVE: NA

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

The vf supports two modes DSCP and priority. After configures DSCP
parameters in the pf, the pf synchronizes the DSCP parameters to the vf.
When multiple TCs are configured for a vf, vf can use the dscp parameter
of the pf to select a queue for data flows. The query and configuration
interfaces on the vf side are not provided. The vf supports dscp only
when the vf supports multi-TCs.
