[2/2] net/bonding: fix selection logic
Checks
Commit Message
From: Krzysztof Kanas <kkanas@marvell.com>
Fix max_index to return uint16_t as it is valid slave_id type.
Arrays agg_count and agg_bandwidth should be indexed by slave_id not by
aggregator port_id.
Fixes: 6d72657ce379 ("net/bonding: add other aggregator modes")

The port_id type has been fixed already with another patch [1] and it has been
merged, but this patch does more,
Can you please send a new version on top of latest next-net?
