Subject: [PATCH net] enic: fix checksum validation for IPv6
Date: Wed, 30 Jan 2019 06:59:00 -0800	[thread overview]
Message-ID: <20190130145900.2614-1-gvaradar@cisco.com> (raw)

In case of IPv6 pkts, ipv4_csum_ok is 0. Because of this, driver does
not set skb->ip_summed. So IPv6 rx checksum is not offloaded.
