I would like to ask about the relation between 802.11 and Ethernet L2 Link layer. Are they dependent of each other? Or can they be seen as independent L2 link layers (with only similarities in their headers)?
When capturing packets in Linux in non-monitor mode on a interface the packets will be displayed as "fake" ethernet frames. In monitor mode the "real" frames look quite different. This is quite confusing. My guessing is that the two link layers are actually totally independent.
In particular I wonder how a packet that comes in on a ethernet interface and goes out on a 802.11 interface transforms when the host is configured as a linux router: For instance is there a one-one mapping between the ethernet 802.1Q vlan tags? Or are there even automatic encapsulation mechanisms in the standard (and therefore the two link layers being coupled to each other) ... etc.
Is the relation of 802.11ad (60Ghz) to ethernet similar as that of the other 802.11 standard to ethernet? // Greetings Konrad
