This update for arp-scan to version 1.9.6 fixes the following issues:

- Update to version 1.9.6 (boo#1154552):
* Use libpcap function pcap_set_immediate_mode() instead of ioctl
calls to ensure packets are delivered immediately. This means
that arp-scan now requires libpcap 1.5.0 or later and will
not work with earlier libpcap versions

- Update to version 1.9.5:
* Updated IEEE OUI and IAB MAC/Vendor files.
* Added new --plain (-x) option to surpress printing of header
and footer text, and only display one output line for each
responding host.
* Use LWP::UserAgent instead of LWP::Simple in get-oui and
get-iab to enable the raw content to be obtained, which avoids
Unicode/UTF-8 issues.
* Added arp-fingerprint patterns for WIZnet W5100 and Cisco IOS
15.0.
