Subject[patch 14/54] e1000: disable polling before registering netdevice
-stable review patch.  If anyone has any objections, please let us know.
---------------------
From: Auke Kok <auke-jan.h.kok@intel.com>

To assure the symmetry of poll enable/disable in up/down, we should
initialize the netdevice to be poll_disabled at load time. Doing
this after register_netdevice leaves us open to another race, so
lets move all the netif_* calls above register_netdevice so the
stack starts out how we expect it to be.
