So the LwIP discards such frames, right?

Thanks

No, lwIP doesn't support it. But it should be easy to add in
src/netif/ethernet.c.

[lwip-users] Double VLAN tagging

[Amena El Homsi]

Hello,

In the eth_type enum, I didn't see the ETHTYPE 0x88a8 referring to the TPID
of service-provider outer S-TAG used when the Ethernet frame have double
VLAN tagging.
Does LwIP support Ethernet frames with double VLAN tagging?

Thanks,
Amena
