Checked in, thanks for reporting, Emil. And thanks for the new patch: turns out my win32 patch.exe had problems with the unix-style patch, so maybe the attachment on lwip-devel would have sufficed, after all :-)

Maybe I should clarify that this is only a patch to fix the broken implementation on HEAD, not to add a more complete implementation...

According to previous mailing list discussion:

[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
