Tobias, thanks for the information. The device on my machine is the Broadcom BCM5721, and the reason why I decided that the driver was at fault is because I found somebody else online with the same problem and that particular model of Broadcom NIC.
Also to re-update the situation, setting it to 100 mbit didn't permanently fix the situation, it just made the occurrances of the problem happen less so I misdiagnosed it as fixed :( Do you have any advice as to what to look for more in-depth? I have replaced some of the switching hardware, but not all of it. The reason why I don't think it is the switch or cables is because direct system-to-system communication works just fine, it's only when I'm doing any sort of packet-forwarding (with lvs-nat or just simple iptables port-forwarding).
