Subject: [PATCH V2 net-next 2/3] net: hns3: add priv flags support to switch limit promisc mode
From: Jian Shen <shenjian15@...wei.com>
Currently, the tx unicast promisc is always enabled when promisc
mode on. If tx unicast promisc on, a function will receive all
unicast packet from other functions belong to the same port.
Add a ethtool private flag to control whether enable tx
unicast promisc. Then the function is able to filter the
unknown unicast packets from other function.
