Merge branch 'develop' of https://gitlab.eurecom.fr/oai/openairinterface5g into NR_F1C_F1U_extensions

We suspected a faulty N310 on obelix. It has been replaced with another
N300 with the same .10.2 addr, but the mgmt_addr changed to .18.16,
corrected in this commit.

Cedric is not sure whether this is a problem, suppress this for the time
being.
