    Thank you for your reply.

    I need to use the bcm5700 driver. Otherwise, I have to reimplemented
    the changes that has been already implemented.

    By the way, I found the reason for this bug and fixed it. It was
    caused by the scheduling of NET_TX_SOFTIRQ. The conflict happens when
    tx softirq is run.
    I have already disabled rx softirq as I am processing the packets at
    the interrupt level.


    Thanks,
    Khaled
