The symptoms sound like the ARP reply is getting lost. I have seen
this on some network cards (especially NetGear FA310TX) where the RX
data is much longer than it should be and is split over multiple input
buffers which confuses the kernel. When you get this symptom, check
arp -an on both machines. I expect that the mips64 box will have the
hardware address of the source machine but the other machine will be
missing the hardware address of the mips64 box.
Doing the traffic in reverse automatically fills in the hardware
address of the machine that the arp request came from. This tends to
hide the RX overrun problem.
