cascaded switch

Hello, I am trying to understand the concept of cascaded switch. I haven't find much information on this topic. Can anyone please explain the general concept, when is it used, and why does the device tree need to know about cascaded switch ? Thank you, ranran

DSA switch

Hello, Is it possible to use switch just like external real switch, connecting all ports to the same subnet ? In our architecture, we prefer that all IPs connected to board shall be in the same subnet. Yet, I am not sure if it is possible with dsa switch, because in dsa the ports are seen in

Q: force netif ON even when there is no real link ?

Hello, We configure external switch in u-boot. The configuration is through mdio (cpu is mac and switch is phy). But in Linux we rather not implement any communication in mdio to switch, but it means that we then don't have the information of link state. Is it possible to force in Linux (by

marvell switch

Hello, I am trying to use marvell switch in linux, Is it that the kernel drivers from marvell switch are used just to enable all ports, or do they also provide APIs to userspace to enable specific ports only. I have not find examples or wiki for marvell switch, so I am not too sure as what are

Hello, I am using intel igb driver in Linux. The driver strip the packet from vlan inofmation. But we need this information in the packet. We tried to change build flag, or see if there is any feature with ethtool that can disable this feature, but nothing helps. Is there any way to achive

smc911 vs smsc911
