netpoll: Add netpoll_tx_running
This patch adds the helper netpoll_tx_running for use within ndo_start_xmit. It returns non-zero if ndo_start_xmit is being invoked by netpoll, and zero otherwise. This is currently implemented by simply looking at the hardirq count. This is because for all non-netpoll uses of ndo_start_xmit, IRQs must be enabled while netpoll always disables IRQs before calling ndo_start_xmit.
