From: Jian Shen <[email protected]>
As the HNS3 driver doesn't update the MAC address directly in
function hns3_set_rx_mode() now, it can't know whether the
MAC table is full from __dev_uc_sync() and __dev_mc_sync(),
so it's senseless to handle the overflow promisc here.
This patch removes the handle of overflow promisc from function
hns3_set_rx_mode(), and updates the promisc mode in the service
task.
