Thanks for your answer. The NIC in question is a Realtek 8139 and indeed, Google told me that a few people have been experiencing similar issues with it. However, that was with old (4.x/5.x) FreeBSD releases, so I'm wondering: is this particular NIC model still causing problems or is it the NIC breaking in some way? The reason I ask is that the machine is a dedicated server over which I have no hardware control, so asking the provider to replace the NIC with another model could be a bit bothersome.
