["Kengo NAKAHARA" <knakahara%netbsd.org@localhost>]

Module Name:    src
Committed By:   knakahara
Date:           Fri Apr  6 10:31:35 UTC 2018

Modified Files:
        src/sys/netipsec: ipsecif.c

Log Message:
Add IPv4 ID when the ipsecif(4) packet can be fragmented. Implemented by hsuenaga@IIJ and ohishi@IIJ, thanks.

This modification reduces packet loss of fragmented packets on a
network where reordering occurs.

Alghough this modification has been applied, IPv4 ID is not set for
the packet smaller then IP_MINFRAGSIZE. According to RFC 6864, that
must not cause problems.
