It is based on the rework done by David Jander which disables the only six messages deep hardware FIFO of the FlexCAN core and instead uses all available mailboxes for reception. Please keep in mind that disabling FIFO mode in FlexCAN disables RTR-reception on i.MX3. Please refer to http://marc.info/?l=linux-can&m=141199785820075&w=2 about the mail I've written to David last year). This needs to be handled. Best regards, Alexander -- Dipl.-Inf.
