Steps to Reproduce the Problem
Start baseboxd with GLOG_v=3.
Connect a switch
Wait some time for netlink events to occur ...
Anlaysis
The logging call in cnetlink.cc on line 1080 includes function calls rtnl_link_get_slave_type(old_link) and rtnl_link_get_slave_type(new_link).
These yield NULL pointers for the triggering netlink message effectively calling std::string_view(NULL) with causes the encountered exception.
