Info screen waits for the first data to arrive. This stalls sometimes on my machine because the netlink command does not complete for some reason. So, set the socket to non-blocking and try again next cycle if no data is available. This needs a small version bump for libnl from 3.2 to 3.2.22 because only since then the call to nl_recvmsgs() returns -NLE_AGAIN. Fixes #120.
I have not included the autogenerated changes to
configure
because I have autotools 2.71 which modifies a lot.Further testing is appreciated.
