Subject: [net-next, v3 1/2] tcp: add SO_PEEK_OFF socket option tor TCPv6

From: Jon Maloy <jmaloy@...hat.com>

When doing further testing of the recently added SO_PEEK_OFF feature
for TCP I realized I had omitted to add it for TCP/IPv6.

I do that here.

    was discovered. Based on feedback from J. Kicinski.
