H A Dip_tunnel_core.cdiff 0eb8eb2f96851e49d54c301aa3b0672706e6b171 Wed Nov 06 03:01:04 CST 2019 Xin Long <lucien.xin@gmail.com> lwtunnel: add options process for cmp_encap

When comparing two tun_info, dst_cache member should have been skipped,
as dst_cache is a per cpu pointer and they are always different values
even in two tun_info with the same keys.

So this patch is to skip dst_cache member and compare the key, mode and
options_len only. For the future opts setting support, also to compare
options.
