driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I6W94W


CVE: NA

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

The patch supports the function of disabling and status query of lane
channels on a port. The patch traverses all covered lanes on the
port and powers off the serdes ds power.
