LED blink rate is based on the traffic load, when tx/rx traffic counts
got reset, we also need to reset the led_tpt to prevent incorrect
blink rate being calculated.
Merge both clear_tx_statistics() and clear_rx_statistics() into
single clear_traffic_statistics() function, when reset the traffic byte
counts, both tx and rx need to be reset at the same time, to make
sure calculated the correct led blink rate.

LED blinking rate is based on tx/rx traffic, the most reasonable place
to do it is after update the traffic byte counts
This fixes the recent LED blinking breakage on 3945 introduced by "iwlwifi:
separate led function from statistic notification"

CSR_INT_COALESCING previously had only one, but now has two single-byte fields.
With only one single-byte field (lowest order byte) it was okay to write via
iwl_write32(), but now with two, an iwl_write32() to the lower order field
clobbers the other field (odd-address CSR_INT_PERIODIC_REG, offset 0x5), and an
iwl_write32() to CSR_INT_PERIODIC_REG could clobber the lowest byte of the
next-higher register (CSR_INT, offset 0x8).
Fortunately, no bad side effects have been produced by the iwl_write32()
usage, due to order of execution (low order byte was always written before
higher order byte), and the fact that writing "0" to the low byte of the
next higher register has no effect (only action is when writing "1"s).
Nonetheless, this cleans up the accesses so no bad side effects might occur
in the future, if execution order changes, or more bit fields get added to
CSR_INT_COALESCING.
Add some comments regarding periodic interrupt usage.

This rewrites the error handling policies in the TX status handler.
It tries to be error-tolerant as in "try hard to not crash the machine".
It won't recover from errors (that are bugs in the firmware or driver),
because that's impossible. However, it will return a more or less useful
error message and bail out. It also tries hard to use rate-limited messages
to not flood the syslog in case of a failure.

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.

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.
