[M] Change in ...osmo-epdg[master]: Use gtp_u_kmod to create a gtp tundev

by pespin

Attention is currently required from: laforge, pespin. Hello Jenkins Builder, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/erlang/osmo-epdg/+/35943?usp=email to look at the new patch set (#7). The following approvals got outdated and were removed: Code-Review+1 by laforge, Verified+1 by Jenkins Builder Change subject: Use gtp_u_kmod to create a gtp tundev ...................................................................... Use gtp_u_kmod to create a gtp tundev Adding gtp_u_kmod app in osmo_epdg.app.src makes the module app started and create gtp tunnel based on config file upon startup. No other operation is done yet on the tunnel, but this step already allows testing by manually creating pdp contexts outside of the app. The module gtp_u_kmod currently creates the tundev interface with name "gtp0" (hardcoded). The module gtp_u_kmod will fail if the gtp tundev is already created, so be sure to have it removed before starting osmo-epdg.
