From e235441f73a6baf1b43da9dde3cb6828ced9d1fe Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Wed, 11 May 2016 14:12:00 +0200 Subject: split bsc_bootstrap_network() in alloc and config For patch clarity, keep some code dup to be removed in a subsequent patch. In the same sense don't change the fact that mncc_sock_init()'s return value is ignored. The global gsm_network instance 'bsc_gsmnet' is basically only used by the VTY, and a future patch will "hide" that global in a vty .c file. In a nutshell, I want to - first allocate a gsm_network, - then initialize the VTY passing the gsm_network pointer, - and then read the config file using the initialized VTY. So far, bsc_bootstrap_network() allocates the gsm_network and reads the config file right away, which only works by sharing the extern bsc_gsmnet pointer, which I would like to uncouple.
