Dear ted,

thanks for replay.

I checked MAC option about 32 bit header alignment. and test system in both situation. (select and un-select alignment in MAC option)

but nothing changed!

I also removed the two first byte of tx_frame in c source code. (which is used for 32 bit alignment).

Again i just see that register 'aFrameCheckSequenceErrors' and 'aAlignmentErrors' increment in each send when i'm in loop back mode.
