From c631c696823cdddbf3c683c3b78812ecba31c350 Mon Sep 17 00:00:00 2001 From: Jian Shen Date: Fri, 24 Apr 2020 10:23:11 +0800 Subject: [PATCH] net: hns3: refactor the promisc mode setting 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.
