Since eepro100 just uses a fixed set of RX buffers in the > ring (ie. the DMA links are never changed) it works.
eepro100 does a copy if pkt_len < rx_copybreak, otherwise it send up the skb and allocates and links a new one in it's place (see speedo_rx_link). So I would say e100 and eepro100 are the same for >= rx_copybreak. Why does one work and not the other? Is it because the RFD is aligned in eepro100? Russell, what happens with modprobe eepro100 rx_copybreak=0? -scott - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
