| Subject: [PATCH] ARM: dts: BCM5301X: correct RX delay and enable flow control |
| on Asus RT-AC88U |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| 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. |
