Subject: udpv6: Fix the checksum computation when HW checksum does not apply

From: Subash Abhinov Kasiviswanathan <[email protected]>

[ Upstream commit 63ecc3d9436f8012e49dc846d6cb0a85a3433517 ]

While trying an ESP transport mode encryption for UDPv6 packets of datagram size 1436 with MTU 1500, checksum error was observed in the secondary fragment.

This error occurs due to the UDP payload checksum being missed out when computing the full checksum for these packets in udp6_hwcsum_outgoing().
