Dear Harald,
Sorry to spam the openbsc list with this, but if you (or someone) can
confirm if the Sgsn-emu part of Osmo-GGSN utilizing the kernel GTP
module or not, that would be lovely.
FYI, I was not able to pass more than 280Mbit and the sgsn-emu process
was maxing out a single core. Based on this I suspect that it does not
use the kernel GTP module. I have seen some commits that indicates
preparation work for this feature, but it is unclear at least to me,
if this was finished or not. In the Osmo-GGSN.cfg example config I can
see the config option for kernel GTP, but not in the sgsn-emu.cfg
example.
Regards,
Csaba
