Subject: Re: [RFC PATCH net-next 00/11] net: remove disable_irq() from
 ->ndo_poll_controller

Adding a new spinlock to every interrupt service routine is
simply a non-starter.

You will certainly have to find a way to fix this in a way
that doesn't involve adding any new overhead to the normal
operational paths of these drivers.

Thanks.
