Make sure to read the last byte of EEPROM descriptor. Previously

Browse Source 
the last byte of the ethernet address was not read which in turn
resulted in getting 5 out of the 6 bytes of ethernet address and
always returned ENOENT. I did not notice the bug on FPGA version
because of additional configuration data in EEPROM.
