Sends a gratuitous ARP Reply\n to 192.168.2.5 telling that the MAC Address of 192.168.2.3 is its own MAC.\n```javascript\narp.poison('192.168.2.5', '192.168.2.3')\n```\n\n#### Available Options\n###### Send API\n```javascript\n  'hw_type': Hardware Type ([0x00, 0x01] -\u003e Ethernet]), // Array\n  'proto_type': Protocol Type ([0x08, 0x00] -\u003e IPv4), // Array\n  'hw_len': Hardware Length [0x06],// Array\n  'proto_len': Protocol Length [0x04], // Array\n  'op': Type of ARP Operation [request, reply], // String\n  'src_ip': Source IP (192.168.1.2), // String\n  'dst_ip': Destination IP (8.2.3.1), // String\n  'src_mac': Source MAC (8f:3f:20:33:54:44), // String\n  'dst_mac': Destination MAC (02:86:32:1f:2e:7c) // String\n```\n\n#### Debug\n\n    $ sudo DEBUG=arpjs:* node example.js\n\n#### Prerequisite\n\n*  **Libpcap**, used by node-pcap. We use LIBPCAP's send binding for ARP packets.\n\n#### Platforms tested (Works on platforms with libpcap installed)\n\n*  **Mac OSX** - 10.9.2\n*  **Ubuntu** - 12.04\n\n#### Modules used / Credits\n* [node_pcap](https://github.com/mranney/node_pcap)\n* [node-ip](https://github.com/indutny/node-ip)\n* [getmac](https://www.npmjs.org/package/getmac)\n* [debug](https://www.npmjs.org/package/debug)\n\n#### License\n\nThe MIT License (MIT)\n\nCopyright (c) 2014 Ahamed Nafeez\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and associated documentation files (the \"Software\"), to deal\nin the Software without restriction, including without limitation the rights\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\ncopies of the Software, and to permit persons to whom the Software is\nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
