pfSense

Using the hme driver in version 2.1 with part# 501-5406-07 Sun Quad Fast Ethernet PCI card. Once configured, the ports operate normally until link is lost due to cable unplugged. Upon reconnecting the cable, the port begins an endless loop of constantly resetting at an irregular rate of a few seconds interval. If the port is configured statically, pinging the gateway will alternate between normal return when link light is on to "no route to host" when link light is off. This condition is usually accompanied by console error "arprequest: cannot find matching address." Following is System Log sample after cable for hme0 configured as WAN DHCP is reconnected:
