Okay the message is printed on line 575 of "ins_eth_ocm.c". 

//Check for busy flag
        if(result & ETH_OCM_INT_MASK_BUSY_MSK){
       # if (ETH_OCM_DBG_LVL >= 3)        
            dprintf("Frame dropped: too busy to receive\n");
       # endif
            dev->info->netp->n_mib->ifInDiscards++;
        }

So if everything is working properly and if memory serves me correctly, the MAC should only set that BUSY_MSK flag if a packet comes in and the receive FIFO is full. The MAC then discards the packet and sets the error bit in the descriptor.

So we need to find out why this is happening.
