Hi all,
I have added a function inside kernel in netif_rx(). I want to block
all the ethernet interrupts till this function is executed.
How do we block and unblock the interrupts?
Thanks in advance,
Regards,
Sureshkumar K.

Like line 1002 of ../linux/net/core/dev.c
spin_lock_irqsave(&netdev_fc_lock, flags);
blocked_code();
spin_unlock_irqrestore(&netdev_fc_lock, flags);
