[rbridge] Trivial question about FCS in Figure 3 of current protocol draft

[Radia Perlman]

Figure 3 (bottom of page 9) has "Ethernet FCS". Since there are two 
Ethernet headers
(inner and outer), wouldn't there be two Ethernet FCS's? Should the 
diagram simply
omit "Ethernet FCS" or put it twice? Or is it correct somehow and I'm 
not looking at it right,
or do we actually intend to omit the inner Ethernet frame's FCS?

Thanks,

Radia
