I'm not sure if converting it to NAPI would solve it, or just move
the problem elsewhere - IOW, move it from "we need to drop the packet
because we couldn't allocate a skb" to "the hardware dropped the packed
because the FIFO was full."

Yes, I'm intending giving it a go, once I've a spare moment to build
a kernel for the platform etc. It runs root NFS, so should be a good
test for it.
