Subject: [PATCH] e1000: Don't enable polling in open() (was: e1000: assertion
	hit in e1000_clean(), kernel

Herbert Xu wrote:
"netif_poll_enable can only be called if you've previously called
netif_poll_disable.  Otherwise a poll might already be in action
and you may get a crash like this."

Removing the call to netif_poll_enable in e1000_open should fix this issue,
the only other call to netif_poll_enable is in e1000_up() which is only
reached after a device reset or resume.
