Subject: Re: [PATCH v2] NetworkPkg/Ip6Dxe: Clean the invalid IPv6 configuration during driver start.
Date: Tue, 12 Feb 2019 01:04:31 +0000	[thread overview]
Message-ID: <B1FF2E9001CE9041BD10B825821D5BC58B6E691B@SHSMSX103.ccr.corp.intel.com> (raw)

Hi, Jiaxin

I think the Ip6Cfg->SetData() may return other error, which not only because invalid config data is used. Why not just check the config data in Ip6ConfigReadConfigData()?

BestRegards
Fu Siyuan
