Subject: [net-next PATCH 2/6] net: dsa: mt7530: move pkt size and rx err MIB counter to rmon stats API
Date: Thu, 10 Apr 2025 18:30:10 +0200 [thread overview]
Message-ID: <20250410163022.3695-3-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20250410163022.3695-1-ansuelsmth@gmail.com>
Drop custom handling of packet size and RX error MIB counter and handle
them in the standard .get_rmon_stats API
The MIB entry are dropped from the custom MIB table and converted to
a define providing only the MIB offset.
