> +Link Bonding for mode 4 (802.3ad)
> +=================================
> +
> +This test plan is mainly to test link bonding mode 4(802.3ad) function
> +via testpmd.

> +link bonding mode 4 is IEEE 802.3ad Dynamic link aggregation. Creates
> +aggregation groups that share the same speed and duplex settings.
> +Utilizes all slaves in the active aggregator according to the 802.3ad
> +specification. DPDK realize it based on 802.1AX specification, it
> +includes LACP protocal and Marker protocol. This mode requires a switch
> +that supports IEEE 802.3ad Dynamic link aggregation.

> +Requirements
> +------------
> +
> +#. Bonded ports shall maintain statistics similar to normal port.
> +
> +#. The slave links shall be monitor for link status change. See also the concept
> +   of up/down time delay to handle situations such as a switch reboots, it is
> +   possible that its ports report "link up" status before they become usable.
> +
> +#. Upon unbonding the bonding PMD driver must restore the MAC addresses that
> the
> +   slaves had before they were enslaved.
> +
> +#. According to the bond type, when the bond interface is placed in promiscuous
> +   mode it will propagate the setting to the slave devices.
> +
> +#. LACP control packet filtering offload. It is a idea of performance
> +   improvement, which use hardware offloads to improve packet classification.
> +
> +#. support three 802.3ad aggregation selection logic modes (stable/bandwidth/
> +   count). The Selection Logic selects a compatible Aggregator for a port, using
> +   the port LAG ID. The Selection Logic may determine that the link should be
> +   operated as a standby link if there are constraints on the simultaneous
> +   attachment of ports that have selected the same Aggregator.
