I went through the above patch, It seems to me that there was no fundamental problem that stopping us from implementing it in the dma layer basing on Eric' patch if Eric is no longer interested in working on a newer version? It is just that if we allow every subsystem and driver using dma API doing their own trick of skipping dma sync, then there is less willing to implement it in the dma layer. _______________________________________________ Intel-wired-lan mailing list [email protected] https://lists.osuosl.org/mailman/listinfo/intel-wired-lan
