Hi, I'm hoping someone can help me with this ... The DCAN module I'm testing with supports 64 CAN messages and DMA. The combined c_can/d_can driver seem to only support 16 RX message objects and no DMA (as far as I can tell). I noticed that older Linux version (3.1) implemented a separate d_can driver that supports both. I'm wondering why these were removed from the latest c_can/d_can files. The reason for this question is I'm seeing frame losses and I think it is due to the driver. Increasing the socket buffer sizes did not have any effect; the number is overruns was still pretty large. Any feedback would be appreciated. Thanks, Elenita
