Module Name:    src
Committed By:   rin
Date:           Wed Dec 12 01:53:52 UTC 2018

Modified Files:
        src/sys/netinet: ip_output.c
        src/sys/netinet6: ip6_output.c

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.
