[PATCH net] Revert "net: hns3: fix pause config problem after autoneg disabled"

From: Guangbin Huang
Date: Thu Oct 28 2021 - 10:10:56 EST


This reverts commit 3bda2e5df476417b6d08967e2d84234a59d57b1c.

According to discussion with Andrew as follow:
https://lore.kernel.org/netdev/09eda9fe-196b-006b-6f01-f54e75715961@xxxxxxxxxx/

HNS3 driver needs to separate pause autoneg from general autoneg, so revert
this incorrect patch.
