I had no luck with/without TSO either but on tg3.
I disabled the on-disk-caching component of the application and it now runs
without page allocation errors. Currently it is running smoothly at ~500mbit/s
and ~80kpps in each direction at ~44k interrupts/s, so the problematic
combination seems to be many open files, high i/o transaction rate or
troughput and heavy networking load. (tso currently on)
Caching on ext2-fs in general seemed to generate less page allocation errors
than on xfs and none of the traces i looked over so far showed involvement
of the filesystem i.e. were all triggered by alloc_skb.
