Setting CONFIG_GMAC_TX_DELAY=3 (or actually, the moral equivalent on v2014.10, i.e removing the ifdef BANANPI) resulted in non-functional tftp from u-boot (luckily I tried it on a local board first!). Using 0, 1, or 2 seems to work from u-boot at least. I've not tried anything more aggressive, my local board didn't have issues to start with though. I'm going to triple check my remote recovery procedures and then do some experiments on one of the problematic boards.
