From 2d5066fc175ea77a733d84df9ef414b34f311641 Mon Sep 17 00:00:00 2001 From: Jian Shen Date: Thu, 4 Jul 2019 22:04:20 +0800 Subject: [PATCH] net: hns3: enable broadcast promisc mode when initializing VF For revision 0x20, the broadcast promisc is enabled by firmware, it's unnecessary to enable it when initializing VF. For revision 0x21, it's necessary to enable broadcast promisc mode when initializing or re-initializing VF, otherwise, it will be unable to send and receive promisc packets.
