[lwip-devel] VLAN (IEEE 802.1q) support in lwIP 1.4.0_rc2

Hi

 

Has there been any discussion about where to go with VLAN-support in lwIP? The current #define ETHARP_VLAN_SUPPORT only seems to aim at handling incoming tagged packets, and it seems rather broken…

 

Is it of any interest to add a complete VLAN-handling with tagging of outgoing packets and VLAN-id assignment per netif? Of course this could be implemented in a netif-driver, but at least when sending packets the VLAN “injection” would result in more overhead than having it in the stack.

 

I’d be happy to help out with a patch if dev-team think this is something that belongs in lwIP…

 

Best regards

Emil Ljungdahl
