ARP-SCAN not reliable with WIFI devices - arp-scan Options needed

[3615JMD]

The default arp-scan parameters does not perform well with my wifi devices. Most of the wifi devices shows in the "offline" list. I have checked by launching arp-scan manually that with the following parameters, the scan reported all wifi devices:

arp-scan -gNlx -I eth0 --retry 5 --interval 50

Of course the scan takes more time, but as it is automatic it does not matter.

@aceberg : could you offer the possibility to add extra parameters after the interface name ? This would also helps people wanting to scan VLANS. see issue #47 for a possible solution.

Done in v2.0.1 - see docs/VLAN_ARP_SCAN.md for a how-to.
