Re: an interesting CAN driver issue

But when I replaced the vector CAN Card XL with CAN Card X, the frames

The only viable conclusion to be drawn from that is that something about your CanCard X (the card itself, the drivers you're using with it, or its firmware) is plain and simply broken.

after so much debugging I found that the DLC register was creating the
problem. I wanted to transmit always an 8 bytes long frame. I was
putting the value of dlc as -->> DLC_Reg |= 0x08;

When I changed the implementation to -->> DLC_Reg |= 0x08;

You're making no sense whatsoever. You changed it, to the exact same thing, and behaviour changes?
