<div class="bz_comment_block">
<pre class="bz_comment_text">When dedicated queues are enabled on a bond interface by calling
rte_eth_bond_8023ad_dedicated_queues_enable(), DPDK eventually starts
repeatedly loggin "tx_machine(580) - Failed to allocate LACP packet from pool".
According to the code of tx_machine(), this log entry means that the mbuf pool
created to send LACP packets (i.e. port->mbuf_pool) is exhausted.
The problem occurs about 10 minutes after my application (i.e.
<a href="https://github.com/AltraMayor/gatekeeper">https://github.com/AltraMayor/gatekeeper</a> ) starts, and I can reproduce it with
one or two members in the bond interface. The problem does not occur if I
remove the call to rte_eth_bond_8023ad_dedicated_queues_enable().
