Harald Welte gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/4900
to look at the new patch set (#2).
osmo-mgw: Use libosmocore socket abstraction
There's no need for us to use the sockets API directly: We have
pretty nice socket helper functions in libosmocore, let's make
use of them.
