Subject: [PATCH AUTOSEL 5.1 069/375] net: hns3: fix pause configure fail problem

From: Sasha Levin <[email-masked]>
Date: Wed, 22 May 2019 15:16:09 -0400

From: Huazhong Tan <[email-masked]>

[ Upstream commit fba2efdae8b4f998f66a2ff4c9f0575e1c4bbc40 ]

When configure pause, current implementation returns directly
after setup PFC without setup BP, which is not sufficient.

So this patch fixes it, only return while setting PFC failed.

Fixes: 44e59e375bf7 ("net: hns3: do not return GE PFC setting err when initializing")
