Can you compare your implementation to etx_fpm/etx_float ? Both are moving 
average implementations of ETX.

etxff_eth is an experimental ETX that handles "perfect" ethernet connections 
as a special "ETX 0.1" case. It's incompatible with the other ETX

Most likely you mixed up code from etx_ff/etx_fpm/etx_float with code from 
etx_ffeth. They use a different packet format to prevent accidental mixing 
(which could create stable routing loops).
