c_can/d_can driver question

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
