This is a recently-discovered regression from commit
0eb609239efdb52a1cea5abca5e3316052071d81 in the ixgbe driver - a fix is in progress.
The code in the diff below[1] of the above commit is the offender,
And adding the code back in solves the immediate problem here.
If this temporary fix doesn't work, please let me know.
Cheers, -Harry
