net: hns3: add support to update flow control settings after autoneg
When auto-negotiation is enabled, the MAC flow control settings is
based on the flow control negotiation result. And it should be configured
after a valid link has been established. This patch adds support to update
flow control settings after auto-negotiation has completed.
