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
