Subject: [PATCH 4.14 117/125] arm: dts: mt7623: add missing pause for switchport

From: Frank Wunderlich <frank-w@...lic-files.de>

commit 36f0a5fc5284838c544218666c63ee8cfa46a9c3 upstream.

port6 of mt7530 switch (= cpu port 0) on bananapi-r2 misses pause option
which causes rx drops on running iperf.

Fixes: f4ff257cd160 ("arm: dts: mt7623: add support for Bananapi R2 (BPI-R2) board")
