[strongSwan] pluto uses which kernel interface

[anand rao]

Hi,

   From the mailing list I found out that PLUTO doesn't have support for PFKEYv2 
kernel interface. 

Can you please let me know which interface does PLUTO uses to communicate with 
XFRM (kernel).
I am using strongswan 4.3.6 version.

Thanks
