Network indicator blinking constantly

I am using a single Windows XP machine to connect to the internet.
Even when I am not using the internet, the network connection tray
icon keeps glowing, indicating data transfer. The McAfee firewall on
my machine does not register any such data transfer.

As per a suggestion in this forum, I installed Ethereal on my machine.

According to Ethereal the data packets are of type "Fibre Channel". I
have appended here one such packet from the log. The log also has a
few ARP packets thrown in.

Thanks in advance.
