 Log Message:
 Simplify logic in ip{,6}_output().
 
 Now, we have M_CSUM_TSOv[46] bit in ifp->if_csum_flags_tx when
 TSO[46] is enabled for the interface. So we can simply check
 whether TSO[46] is required in a packet but missing in the
 interface by (sw_csum & M_CSUM_TSOv[46]).
 
 Note that this is a very rare case where TSO[46] is suddenly
 turned off during a packet passing b/w TCP and IP.
