From: John Wang Date: Wed, 23 Dec 2020 05:55:23 +0000 (+0800) Subject: net/ncsi: Use real net-device for response handler X-Git-Tag: v5.4.89~70 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=56dc7908ed85f03b01938105c3b7768dc07995b5;p=thirdparty%2Fkernel%2Fstable.git net/ncsi: Use real net-device for response handler [ Upstream commit 427c940558560bff2583d07fc119a21094675982 ] When aggregating ncsi interfaces and dedicated interfaces to bond interfaces, the ncsi response handler will use the wrong net device to find ncsi_dev, so that the ncsi interface will not work properly. Here, we use the original net device to fix it.
