[Openswan Users] who calls ipsec_xmit_esp_setup()

[iler_ml at fastmail.fm]

I need to understand the call chain of rcv and xmit in the ipsec code.
The rcv call chain is understandable. I'm trying to understand now how
ipsec_xmit_esp_setup() is called. It is registered as member
'xmit_setup'.

But nowehre a call to proto_funcs->xmit_setup can be found. Can anyone
shed a light on where proto_funcs->xmit_setup is called, or where
ipsec_xmit_esp_setup() is called ?

Thanks
Yakov Lerner
