Subject: [PATCH net-next 3/7] net: hns3: optimize the code when update the tc info

From: GuoJia Liao <liaoguojia@...wei.com>

When update the TC info for NIC, there some differences
between PF and VF. Currently, four "vport->vport_id" are
used to distinguish PF or VF. So merge them into one to
improve readability and maintainability of code.
