https://gerrit.osmocom.org/c/erlang/osmo-s1gw/+/41531/comment/1c0b1dfe_798ca... : PS2, Line 17: %% * rto_initial - RTO (retransmission time-out) initial, ms (default: 1000)

I'm not sure we want to provide defaults for RTO ourselves, I'd say let the kernel pick them up. […]

I suggest to use our values as defaults, rather than the kernel defaults. A timeout of about 10 minutes makes no sense for S1 link.
