[v2] net/bonding: fix selection logic
Checks
Commit Message
From: Krzysztof Kanas <kkanas@marvell.com>
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")

This change doesn't look right. Did you really want to do this, put the
code outside of the case statement?
