net: hns3: Add vport alive state checking support
Currently there is no way for pf to know if a vf device is alive or not, so PF does not know which vf to notify when reset happens, or which vf's mtu is invalid when vf and pf share the same hardware mtu setting. This patch adds vport alive state checking support, in order to support the above scenario.
