Enable IPsec

============

Default IPsec transformation with ESP encapsulation plus Transport mode

could be enabled by simply setting:



pgset "flag IPSEC"

pgset "flows 1"



To avoid breaking existing testbed scripts for using AH type and tunnel mode,

user could use "pgset spi SPI_VALUE" to specify which formal of transformation

to employ.
