rfc 1042 encapsulation & bridge tunnel

I was studying HostAP code. About encapsulation I've found that the driver
adds in tx and strips in rx (file hostap_hw.c):

- nothing at all (if EtherType is less than 0x600 that is it's a length and
not a type)
- bridge_tunnel_header (Bridge-Tunnel header for EtherTypes ETH_P_AARP and
- rfc1042_header (Ethernet-II snap header RFC 1042 for other EtherTypes)

Is this a standard behaviour? Where can I found the docs about it (besides
rfc 1042)?

Thanks in advance,
