Subject: [PATCH] ARM: dts: BCM5301X: correct RX delay and enable flow control
|
||
on Asus RT-AC88U

|
||
The current 'rx-internal-delay-ps' property value on the Realtek switch
|
||
node, 2000, will be divided by 300, resulting in 6.66, which will be
|
||
rounded to the closest step value, 7. Change it to 2100 to be accurate.
|
||
See ef136837aaf6 ("net: dsa: rtl8365mb: set RGMII RX delay in steps of
|
||
0.3 ns") for reference.
|
||
|
||
Flow control needs to be enabled on both sides of the internal and
|
||
external switch. It is already enabled on the CPU port of the Realtek
|
||
switch so we also enable it on the external switch port of the Broadcom
|
||
switch as well.
