Bug ID	1415
Summary	Calling rte_eth_bond_8023ad_dedicated_queues_enable() leads t= o exhaustion of the LACP packet pool
Product	DPDK
Version	23.11
Hardware	All

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 fr=
om pool".
According to the code of tx_machine(), this log entry means that the mbuf p=
ool
created to send LACP packets (i.e. port->mbuf_pool) is exhausted.

The problem occurs about 10 minutes after my application (i.e.
https://github.com/Alt=
raMayor/gatekeeper ) 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().
