No luck... didn't fix it. Is it fixed in a subsequent release? Are
there any other parameters I can tune?

Can you bump up your input queue depth:
hold-queue 4096 in
and see if they stop.
I don't suspect that is going to help because the ignores
are not increasing that would point to:
CSCse05447
Externally found moderate defect: Resolved (R)
7200 ethernet interfaces should not throttle on input queue full drops
Most likely you are seeing micro burst that are coming in faster
than the CPU can drain the rx ring.
