NETGEAR GSM712F Switch Firmware 2.4.1

Fixes:
- Fixed some corner cases for port-based VLAN application.
- Fixed crash caused by nmap task.
- Fixed a page-misalign problem in the Multicast page in the Web.
- Fixed a bug, which caused telnet to fail sometimes.
- Limited the length of an URL to 255 characters in the Web server.

Enhancements:

- Add IEEE 802.1w (Rapid Spanning Tree Protocol) support. The default mode for STP changed from IEEE 802.1d to IEEE 802.1w.
- Add support for EAP-TLS and EAP-TTLS for 802.1x Port Authentication.
- Add support for RADIUS accounting.
- Add support to allow range of IP address in host IP filter table or SNMP host table.
- Change the firmware upgrade procedure in Net-Save mode that the firmware will be downloaded and saved to the on-board Flash before the switch is rebooted. This solved the problem of upgrade failure when using fiber GBIC.
- Add a new control in SNMP access to allow read access to any host.
- Change SNMP read access from blocked to allowed by all hosts as default.
