please make cfg80211 dependency optional

[christf]

when running l3roamd the kernel module cfg80211 must be loaded otherwise l3roamd exits with the message: "nl80211 not found"

the error message seems to be originating from wifistations.c

106 int nl80211_id = genl_ctrl_resolve(ctx->nl_sock, "nl80211"); 107 if (nl80211_id < 0) { 108 fprintf(stderr, "nl80211 not found.\n"); 109 goto fail; 110 }

should l3roamd really depend on cfg80211 even if the system that it runs on does not contain wifi hardware?

To confirm the problem you can create a file /etc/modprobe.d/cfg80211.conf containing this line:

blacklist cfg80211

Then make sure with rmmod that the module is unloaded and start l3roamd:

$ sudo src/l3roamd -i eth0
Setting up icmp6 interface: 0
nl80211 not found.
Could not open nl80211 socket
