Hello, I'm working on a P1021MDS based board and I have a strange behaviour regarding the TX packets from the gianfar driver (linux 3.0.4-rc5).
Rx is working correctly but Tx is not... in particular I noticed that the buffer descriptors are correctly filled but the packets simply do NOT exit form the TSEC (I looked at TSEC's tx counters)! What is puzzling me is that sometimes both TX and RX work correctly but most of the time only Rx is working! Again, testing the same uImage on a Freescale P1021MDS devboard everything works well! Maybe something related to DMA/RAM coherence?
