They pop up unconditionally just after ifup. If I run tcpdump on the
same LAN I see a lot of multicast/broadcast frames and probably the
error comes out on the reception of them. Also because I figured out
from fec_imx.h that 0x00000886 means:

#define FEC_RBD_LAST		0x0800	/**< Receive BD status: Buffer
is last in frame (useless here!) */
#define FEC_RBD_BC		0x0080	/**< Receive BD status: The
received frame is broadcast frame */
#define FEC_RBD_CR		0x0004	/**< Receive BD status: CRC
error */
#define FEC_RBD_OV		0x0002	/**< Receive BD status: Receive
FIFO overrun */

Best,
Stefano
