Subject: net: hns3: extend the loopback state acquisition time
Patch-mainline: v5.2-rc1
Git-commit: fd85717d2800a352ce48799adcf7037b74df2854
References: bsc#1104353 FATE#326415

The test results show that the maximum time of hardware return
to mac link state is 500MS.The software needs to set twice the
maximum time of hardware return state (1000MS).

If not modified, the loopback test returns probability failure.
