[PATCH net-next 7/8] net: ip_tunnel: remove 'csum_help' argument to iptunnel_handle_offloads
From: Edward Cree <hidden>
Date: 2016-01-08 19:47:46
Subsystem:
ipvs, netfilter, networking drivers, networking [general], networking [ipv4/ipv6], the rest · Maintainers:
Simon Horman, Julian Anastasov, Pablo Neira Ayuso, Florian Westphal, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, David Ahern, Ido Schimmel, Linus Torvalds
All users now pass false, so we can remove it, and remove the code that was conditional upon it.
