Remove the function e1000e_commit_phy() and replace the few calls to it
with the same function pointer that it would call.  The function pointer is
almost always set for the devices that access these code paths so there is
no risk of a NULL pointer dereference; for the few instances where the
function pointer might not be set (i.e. can be called for the few devices
which do not have this function pointer set), check for a valid function
pointer.

The comments here say that the /* Max event is 61 char */ but in 2003 we
changed the event format and now the max event size is 75.  The longest
event is:

	"Discovered %08x (%s) behind %08x {hints %02X-%02X}\n",
         12345678901    23  456789012    34567890    1    2 3
	            +8    +21        +8          +2   +2     +1
         = 75 characters.

There was a check to return -EOVERFLOW if the user gave us a "count"
value that was less than 64.  Raising it to 75 might break backwards
compatability.  Instead I removed the check and now it returns a
truncated string if "count" is too low.

====================
This series contains updates to e1000e only.  All the updates come
from Bruce Allan and most of the patch fix or enable features on
i217/i218.  Most notably is patch 03 "e1000e: add support for IEEE-1588
PTP", which is v2 of the patch based on feedback from Stephen Hemminger.

Also patch 04 "e1000e: enable ECC on I217/I218 to catch packet buffer
memory errors" should be queued up for stable (as well as net) trees, but
the patch does not apply cleanly to either of those trees currently.
So I will work with Bruce to provide a version of the patch which will
apply cleanly to net (and stable) and we can queue it up at that point
for stable 3.5 tree.

The remaining patches are general cleanups of the code.

In rare instances, memory errors have been detected in the internal packet
buffer memory on I217/I218 when stressed under certain environmental
conditions.  Enable Error Correcting Code (ECC) in hardware to catch both
correctable and uncorrectable errors.  Correctable errors will be handled
by the hardware.  Uncorrectable errors in the packet buffer will cause the
packet to be received with an error indication in the buffer descriptor
causing the packet to be discarded.  If the uncorrectable error is in the
descriptor itself, the hardware will stop and interrupt the driver
indicating the error.  The driver will then reset the hardware in order to
clear the error and restart.

Both types of errors will be accounted for in statistics counters.

This batch contains netfilter updates for you net-next tree, they are:

* The new connlabel extension for x_tables, that allows us to attach
  labels to each conntrack flow. The kernel implementation uses a
  bitmask and there's a file in user-space that maps the bits with the
  corresponding string for each existing label. By now, you can attach
  up to 128 overlapping labels. From Florian Westphal.

* A new round of improvements for the netns support for conntrack.
  Gao feng has moved many of the initialization code of each module
  of the netns init path. He also made several code refactoring, that
  code looks cleaner to me now.

* Added documentation for all possible tweaks for nf_conntrack via

* Cisco 7941/7945 IP phone support for our SIP conntrack helper,

* Missing header file in the snmp helper, from Stephen Hemminger.
