Ricoh Aficio GX e5550N Multifunction Network Firmware

Fixes:
- If a DHCP offer Lease Time or Server Identifier is not exactly 4 bytes (as defined by RFC2132), the printer will lose network connectivity until rebooted. This loss of network connectivity only occurred if the printers "DNS Server" setting was manually specified (not determined by DHCP).
- The printer will lose connectivity with the network when trying to resolve a hostname with a DNS server if the reply sent by the DNS server contains an RDLENGTH that does not accurately describe the length of the contents of the RDATA field (in contrast to what has been standardized by RFC1035). This loss of network connectivity only occurred if the printers DHCP setting was "Active".
- Any time the ethernet link goes down > up, the printer will send a gratuitous ARP.
