Be careful, don't mix up ethertype with LSAP.
For some layer 2, there is no LSAP field such as ARP, so 0x0806 is about
ethertype.
For other layer 2, other than ethertype field, there is a field called LSAP.
For some cisco proprietary protocols, such as PAGP, VTP, PVST+, CDP, DTP, and
UDLD, LSAP is 0xAAAA. For CST which is IEEE standard, LSAP is 0x4242.
