i.mx28 ENET1 RX CRC errors

Hi

I'm are getting a CRC error flag every time a frame is rxed on MAC1 (even a good one). This is not observed on MAC0.

We are using custom board. I can't check it my i.MX28EVK, cause it's broken now. Can anyone confirm it?

 

It seems driver just update statistics and don't drop this frame:

/drivers/net/fec.c: fec_enet_rx():

if (status & BD_ENET_RX_CR) /* CRC Error */

dev->stats.rx_crc_errors++;

 

 

We want to drop frames with wrong crc, cause such frames did already reset or hanged our units.
