OK,

You may try to increase your MTU by using "ifconfig rl0 mtu 1580" (for 
example) - Do not forget to add this option in /etc/rc.conf (for boot 
settings)

If it does not solve the problem, the problem could be due to your 
network interface and the "RL" driver itself. In that case, you have to 
shut down the interface and remount it, I agree that it is not a proper 
solution but I saw it on a newsgroup.


Hope this help!

Kind Regards.
