[net-next RFC PATCH 3/4] net: dsa: qca8k: rework mib autocast handling

From: Christian Marangi
Date: Sat Jul 16 2022 - 13:50:46 EST


In preparation for code split, move the autocast mib function used to
receive mib data from eth packet in priv struct and use that in
get_ethtool_stats instead of referencing the function directly. This is
needed as the get_ethtool_stats function will be moved to a common file.
