The Tx unit hang detection code in e1000e detects other hangs caused by
hardware components (e.g. Rx, DMA units), but it is not possible to detect
exactly which component is hung so it has always assumed a Tx unit hang.
When dumping a message to the system log because of a hang, this patch adds
more data to help narrow the cause of the issue and makes the message
non-Tx-specific.  Because this new code reads PHY registers which can
sleep, move it off to a workqueue.  This and all previously existing work
tasks in the driver are now cancelled when the driver is removed.

It was pointed out a pm_qos DMA latency requirement set when the driver is
loaded when parts that support early receive of jumbo frames are probed
could have that requirement overidden if another part supported by the
driver (one that does not support early receive of jumbo frames) is probed
later.  Change the DMA latency requirement to be per-interface if needed
instead of per driver.

The driver was only updating MII stats when an LSC up was detected and
the interface had not already been reported up to netdev. This meant
MII stats returned in response to an SIOCGMIIREG ioctl would always
show a link up if it had ever been up. This was misleading the networking
daemon guessnet, which uses this ioctl, into making improper network port
selections.
This fix adds a call to e1000_phy_read_status() to actively read the
mii stats before responding to the SIOCGMIIREG ioctl.

Copper links with WoL or management enabled (any condition which prevents
the phy from being powered down when the interface is taken down) were
always reporting link-up when the interface had been taken down. This
is because when the interface is taken down (ifconfig ethx down),
interrupts are disabled. With no interrupts, there is no LSC interrupt,
which is normally required to set "get_link_status", which instructs the
driver to query the device for link state. The fix is to force
get_link_status to true if the interface is not up.
