net: hns3: add support to get/set 1d torus param 

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I97T47


CVE: NA

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

Two network ports on a single chip can be physically connected to form
a 1d torus topology. TCP/UDP and RDMA communication between chip nodes
can be implemented without switches.The patch provide interfaces for
getting/setting 1d torus param.
