Subject: [PATCH net-next v2 4/9] r8169: move disabling interrupt coalescing to RTL8169/RTL8168 init

From: Heiner Kallweit <[email-masked]>
Date: Wed, 28 Aug 2019 22:26:13 +0200

RTL8125 doesn't support the same coalescing registers, therefore move
this initialization to the 8168/6169-specific init.
