TSE and scatter-gather dma problem

Some data was transmitted via ethernet now: as I said in previous post, sgdma was initialized incorrectly.

But while catching the packets with Wireshark, I see that packets content isn't correct.

Besides that the packet was transmitted only twice (instead of infinite sending), after 2 transmissions code never comes to tx_done++, so it is looped in while(tx_done == 0);

I have attached zip-code of source files.

The only correct information is the source mac (00-11-22-33-44-55)

All other bytes should be 0xA5 (as initialized), but in fact I see such packet:

CC CC A5 A5 CC CC 00 11 22 33 44 55 CC CC A5 A5 CC CC A5 A5 CC CC A5 A5 CC CC

and so on...

Total length is also correct (128 bytes).

I have no ideas, what happens...
