MT7981: ethernet issue with MT7531

[SuperKali]

Hi @padavanonly,

I noticed a huge problem with one of my routers with MT7981 chips connected through the MT7531 switch.

As you can see from the attached video, it seems that Ethernet performance is slower than WiFi.

What could be causing this?

Thank you very much for your support.

@padavanonly i temporary reverted to 1934579

seems like more faster but some issue, like packet loss 50% and this is wifi:

Upload your kernel log. In addition, there is a compatibility issue between DSA and HNAT's ext acceleration. I haven’t found a good solution, so this problem might be unsolvable. If you disable HNAT, the speed of your 7531 will be restored

Make sure use this commit as source code.

@padavanonly How not?? But if we also have try it

Have you ever tested it?

@padavanonly With this logic lans works at full speed but i need to put eth1 on br-lan, it can be bypassed?

void ppd_dev_setting(void)
 {
	 br_dev = __dev_get_by_name(&init_net, "br-lan");
		 eth1_dev = __dev_get_by_name(&init_net, "eth1");
		 atomic_set(&eth1_in_br, 0);
				if (br_dev && eth1_dev) {
						 struct net_device *dev;
						 struct list_head *pos;
						 netdev_for_each_lower_dev(br_dev, dev, pos) {
								 if (dev == eth1_dev) {
								 atomic_set(&eth1_in_br, 1);
								 break;
								 }
						 }
				 }
 
		 if (atomic_read(&eth1_in_br)){
						 printk("eth1 in br-lan");
						 hnat_priv->g_ppdev = __dev_get_by_name(&init_net, "eth1");                        
			 }
				 else {
					 printk("eth0 in br-lan");
					 hnat_priv->g_ppdev = __dev_get_by_name(&init_net, "eth0");
					 }
 }

It seems that you have to put eth1 into br-lan if it is used as ppd interface.

@padavanonly In fact, by putting the old logic and putting eth1 on br-lan everything works correctly
