4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Govindarajulu Varadarajan <gvara...@cisco.com>
[ Upstream commit 7596175e99b3d4bce28022193efd954c201a782a ]
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.
