Jordan Whited 052af4a807 tun: use correct IP header comparisons in tcpGRO() and tcpPacketsCanCoalesce() 
tcpGRO() was using an incorrect IPv4 more fragments bit mask.

tcpPacketsCanCoalesce() was not distinguishing tcp6 from tcp4, and TTL
values were not compared. TTL values should be equal at the IP layer,
otherwise the packets should not coalesce. This tracks with the kernel.
