After upgrading Gatekeeper's DPDK, Gatekeeper is not booting with bond interfaces. This issue is identified with log entries similar to the one below:
memzone eth_p1_q0_rx_ring does not justify the requested attributes

The example log entry above and others may differ on the name of the queue that triggers the issue. In the example above, the name of the queue is eth_p1_q0_rx_ring.

The solution consists in allocating the RX and TX queues on the same NUMA socket to which the underlying Ethernet device is connected; see configure_queue() edited in this pull request for more details. Gatekeeper was using the NUMA node of the block responsible for the queue.

Here is a backtrace when the issue is triggered to serve as a reference:
