CAN frame types of iMX6 WinCE

On iMX6 WinCE, the CAN frame type is specified by

 Can_SetConfigString(hCan, L"FrameFormat",    L"standard",     StoreVolatile);

Is it possible to receive both standard and extended frames simultaneously? WIth SJA1000, it can be set to receive both frames.

CanWriteDescriptor(device, 0x80000000, 0xffffffff);	  // Receive all messages

Is MCP2515 or iMX6 native CAN controller limited to receive only one type frame at one time?

I also did test on Apalis iMX6 with Linux using iMX6 native flexcan. It is okay to receive both frames.

root@apalis-imx6:~# candump can0
interface = can0, family = 29, type = 3, proto = 1
[   66.752787] random: nonblocking pool is initialized
<0x001> [8] 01 02 03 04 05 06 07 08
<0x00000001> [8] 01 02 03 04 05 06 07 08

The current implementation of our CAN library can’t receive both frame types at the same time.
