When the VF shares the same TC config as PF, the business
running on PF and VF must have samiliar module.
For simplicity, we are not considering VF sharing the same tc
configuration as PF use case, so this patch removes the support
of TC configuration from VF and forcing VF to just use single
TC.

hns3_client_setup_tc in enet is for updating TC configuration to

This patch removes the hns3_nic_set_real_num_queue from
hns3_setup_tc in enet, and call hclge_client_setup_tc to update
TC configuration to stack with netdev down, because the netdev

shared buffer. The remaining buffer size should be at
least bigger than or equal to the shared_std, which is the

currently if the remaining buffer size is equal to the
