Sorry, that was an honest mistake. Let's say I want to tweak push_vlan to add a new tag, even if theres an existing one- I saw that there's a check to see if there's a vlan header on the frame and if so, it 'pushes down' the current header, creating space for a new one. If I drop it, will a new header get created?
I'm trying to figure out which code I need to tweak in order to support, even partially, two vlan headers. (I only want to access the outer one, never the inner). After that I can start working on a full implementation. Any thoughts? Thanks!
