Subject: [PATCH v2 4/4] net: thunderx: Allow IPv6 frames with zero UDP checksum
Date: Tue,  7 Mar 2017 18:09:11 +0530	[thread overview]
Message-ID: <1488890351-18493-5-git-send-email-sunil.kovvuri@gmail.com> (raw)
In-Reply-To: <1488890351-18493-1-git-send-email-sunil.kovvuri@gmail.com>

From: Thanneeru Srinivasulu <tsrinivasulu@cavium.com>

Do not consider IPv6 frames with zero UDP checksum as frames
with bad checksum and drop them.
