Subject: ipv4: tcp: set unicast_sock uc_ttl to -1
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=0980e56e506b;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

ipv4: tcp: set unicast_sock uc_ttl to -1

Set unicast_sock uc_ttl to -1 so that we select the right ttl,
instead of sending packets with a 0 ttl.

Bug added in commit be9f4a44e7d4 (ipv4: tcp: remove per net tcp_sock)
