For now, I've patched one front end server with:
/usr/src/sys/dev/e1000/if_igb.h:#define IGB_MAX_RXD 4096 * 4
And adjusted hw.igb.rxd: 8192
So far so good, been running in production for a couple of hours so the
"smoke test" for this setting seems to be happy.
We'll continue to adjust and test tomorrow during higher load
