I have no tc rules which select output queue 16 (I have no tc rules at all
in fact). 

Output of /proc/net/bonding/bond0 below.  The bond consists of two Intel
igb nics, which only have 8 queues.  Note, however, that eth0 is an ixgbe,
which has 16 queues:

ixgbe 0000:0b:00.0: Multiqueue Enabled: Rx Queue count = 16, Tx Queue count = 16

which may answer your question as to what is selecting queue 16.
