Ethernet II / LLC

Hello,

frame can have such a combination or maybe it's a misinterpretation of the program.

I think this frame 802.3/802.2/SNAP

can be wrong?

0x8100 is the Ethertype for a VLAN tag following the Ethernet II header, so that seems to be correct. In that VLAN tag is a length value less than 1500 so the next part is LLC. Seems all fine to me.

There is a VLAN tag between the Ethernet II header. Think of it as two Ether types following each other. The first says "Ethernet II" and points to a VLAN tag, the seconds (VLAN tag) says "next is 802.3", so that's fine, too.
