 Are you sure? r339338 says

======
Finishes the conversion of the 40Gb Intel Ethernet drivers to iflib(9) for
FreeBSD 12.0, and fixes numerous bugs in both ixl(4) and iavf(4).
======

 It doesn't touch e1000 or ix (ixgbe) drivers. I've updated to r339345 and
all three files:

sys/dev/e1000/em_txrx.c
sys/dev/e1000/igb_txrx.c
sys/dev/ixgbe/ix_txrx.c

 contain this buggy "budget == 1" optimization.
