Thanks for the reminder: You are correct, at least in the uplink case
(MS->GGSN) where there is mobility of the MS. In the downlink case
(GGSN->MS), which is the "sending" part for the kernel GTP code used at
a GGSN, I'm not sure if that theory holds true in reality.
Do you agree that the current behavior of not using automatic source
address selection for encapsulated GTP packets but rather using the
source address of the socket is intended?
Do you further agree that the dst_cache support patch by Tom retains
that intended behavior and it should be merged?
