[PATCH 2/6] net/txgbe: add flush operation for Amber-Lite NICs

[Zaiyu Wang]

Add flush operation for AML NICs to ensure configuration takes effect.
The flush forces hardware to apply new settings right after driver
updates. Missing flush may cause potential negative impacts as
configurations could remain pending.
