This patch set fixes problem when mbufs are not released back to the
original memory pool during Rx queue relese call leading to mbufs
"leakage".

This issue happens when device stop (rte_eth_dev_stop()) will be called
after device start (rte_eth_dev_start()) without any incoming packets
received since device start. In this case both rxq->rx_tail and
rxq->rxrearm_start equal to 0 and release cycle will not be executed.
On the next device start (rte_eth_dev_start()) new set of mbufs for the
RX queue will be allocated.

  net/ixgbe: fix mbufs leakage during Rx queue release
  net/i40e: fix mbufs leakage during Rx queue release

Applied to dpdk-next-net/rel_16_11

I don't know the underlying code well enough,

Me, neither.

but given the description I'd
expect that qualifies for the stable tree?

But, yes, I agree with Christian.

Set stable@dpdk on cc.

Thanks for doing that.
