Subject: [PATCH v2 net-next 12/14] net: mscc: ocelot: rename aggr_count to num_ports_in_lag
Date: Sat, 16 Jan 2021 02:59:41 +0200	[thread overview]
Message-ID: <20210116005943.219479-13-olteanv@gmail.com> (raw)
In-Reply-To: <20210116005943.219479-1-olteanv@gmail.com>

From: Vladimir Oltean <vladimir.oltean@nxp.com>

It makes it a bit easier to read and understand the code that deals with
balancing the 16 aggregation codes among the ports in a certain LAG.
