(Get the code!)
During the attemptions to ping or other actions, which mean the adoption of the package with the MTU size of interface (1500), the frame isn't accepted and there is an increasing of value error and frame by one in ifconfig output. By practical consideration was cleared up, that 4 last bytes aren't able to get throught, as the maximum size of delivered ip package can't be more than 1496 bytes (from 1500 supposed to be), and accordingly to it, the size of the ethernet frame can't be more than 1510 (from 1514 supposed to be) bytes.The tests of this hardware in the alternative operating system (windows 7) have shown us the positive result and pointed on the correct work of hardware and the communication medium.
