There are several places/cases that got overlooked in regards to
SOCK_SUPPORT_ZC. We're lacking the flag for IPv6 UDP sockets and
accepted TCP sockets. We also should clear the flag when someone
tries to hijack a socket by replacing the ->sk_prot callbacks.

Pavel Begunkov (3):
  udp: advertise ipv6 udp support for msghdr::ubuf_info
  net: remove SOCK_SUPPORT_ZC from sockmap
  net/ulp: remove SOCK_SUPPORT_ZC from tls sockets

Stefan Metzmacher (1):
  net: also flag accepted sockets supporting msghdr originated zerocopy
