alx: add statistics

Currently, the alx driver doesn't support statistics [1,2]. The
original alx driver [3] that Johannes Berg modified provided
statistics. This patch is an adaptation of the statistics code from
the original driver to the alx driver included in the kernel.

v4:
 - modified the assignements of hw stats to netstats (Ben Hutchings)
 - added comments to describe the stats fields (copied from atlx)

v3:
 - renamed __alx_update_hw_stats to alx_update_hw_stats (Stephen Hemminger)

v2:
 - use u64 instead of unsigned long  (Ben Hutchings)
 - implement ndo_get_stats64 instead of ndo_get_stats (Ben Hutchings)
 - use EINVAL instead of ENOTSUPP  (Ben Hutchings)
 - add BUILD_BUG_ON to check the size of the stats (Johannes Berg, Ben
   Hutchings)
 - add a comment regarding persistence of the stats (Stephen Hemminger)
 - align assignments in __alx_update_hw_stats

Intel Wired LAN Driver Updates

This series contains updates to i40e and now i40evf.

Most notable is Jacob's patch to add PTP support to i40e.

Mitch cleans up additional memcpy's and use struct assignment instead.
Then fixes long lines to appease checkpatch.pl.  Mitch then provides
a fix to keep us from spamming the log with confusing errors.  If you
use ip to change the MAC address of a VF while the VF driver is loaded,
closing the VF interface or unloading the VF driver will cause the VF
driver to remove the MAC filter for its original (now invalid) MAC
address.

Jesse cleans up macros which are no longer needed or used.

I (Jeff) cleanup function header comments to ensure Doxygen/kdoc works
correctly to generate documentation without warnings.

Anjali fixes a bug where ethtool set-channels would return failure when
configuring only one Rx queue.  Then fixes a bug where the driver was
erroneously exiting the driver unload path if one part of the unload
failed.

Shannon fixes if the IPV6EXADD but is set in the Rx descriptor status,
there was an optional extension header with an alternate IP address
detected and the hardware checksum was not handling the alternate IP
address correctly.  Then adjusts the ITR max and min values to match
the hardware max value and recommended min value.  Shannon makes sure
to clear the PXE mode after the adminq is initialized.

v2:
 - fix patch 14 "i40e: enable PTP" to address Richard Cochran's spelling
   catch and Ben Hutchings Kconfig, SIOCGHWTSTAMP and sizeof() suggestions
 - added Paul Gortmaker's i40evf fix patch
v3:
 - fix patch 14 "i40e: enable PTP" to address Ben Hutchings concerns about
   a race with PTP init and cleanup and i40e_get_ts_info().

If the IPV6EXADD bit is set in the Rx descriptor status, there
was an optional extension header with an alternate IP address
detected.  The HW checksum offload doesn't handle the alternate
IP address correctly so likely comes up with the wrong answer.
Thus, if the bit is set we ignore the checksum offload value.

If you use ip to change the MAC address of a VF while the VF
driver is loaded, closing the VF interface or unloading the VF
driver will cause the VF driver to remove the MAC filter for its
original (now invalid) MAC address. This would cause the PF
driver to kick an error message to the log, and back to the VF
driver.

Since the VF driver has not really done anything naughty, let's
not punish it. Don't check for MAC address overrides on the
delete operation, just make sure it's a valid address. This keeps
us from spamming the log with confusing errors.

====================
Make tcp-metrics source-address aware

Currently tcp-metrics only stores per-destination addresses. This brings
problems, when a host has multiple interfaces (e.g., a smartphone having
WiFi/3G):

For example, a host contacting a server over WiFi will store the tcp-metrics
per destination IP. If then the host contacts the same server over 3G, the
same tcp-metrics will be used, although the path-characteristics are completly
different (e.g., the ssthresh is probably not the same).

In case of TFO this is not a problem, as the server will provide us a new cookie
once he saw our SYN+DATA with an incorrect cookie.
It may be (in case of carrier-grade NAT), that we keep the same public IP but
have a different private IP. Thus, we better reuse the old cookie even if our
source-IP has changed. However, this scenario is probably very uncommon, as
carriers try to provide the same src-IP to the clients behind their CGN.

Patches 1 + 2 add the source-IP to the tcp metrics.

Patches 3 to 5 modify the netlink-api to support the source-IP. From now on,
when using the command "ip tcp_metrics delete address ADDRESS" all entries
which match this destination IP will be deleted.

Today's iproute2 will complain when doing "ip tcp_metrics flush PREFIX" if
several entries are present for the same destination-IP but with different
source-IPs:

root@client:~/test# ip tcp_metrics
10.2.1.2 age 3.640sec rtt 16250us rttvar 15000us cwnd 10
10.2.1.2 age 4.030sec rtt 18750us rttvar 15000us cwnd 10
root@client:~/test# ip tcp_metrics flush 10.2.1.2/16
Failed to send flush request
: No such process

Follow-up patches will modify iproute2 to handle this correctly and allow
specifying the source-IP in the get/del commands.

v2: Added the patch that allows to selectively get/del of tcp-metrics based
    on src-IP and moved the patch that adds the new netlink attribute before
    the other patches.

Please pull these updates for the 3.14 stream!

For the mac80211 bits, Johannes says:

"Felix adds some helper functions for P2P NoA software tracking, Joe
fixes alignment (but as this apparently never caused issues I didn't
send it to 3.13), Kyeyoon/Jouni add QoS-mapping support (a Hotspot 2.0
feature), Weilong fixed a bunch of checkpatch errors and I get to play
fire-fighter or so and clean up other people's locking issues. I also
added nl80211 vendor-specific events, as we'd discussed at the wireless
summit."

For the iwlwifi bits, Emmanuel says:

"I have here a rework of the interrupt handling to meet RT kernel
requirements - basically we don't take any lock in the primary interrupt
handler. This gave me a good reason to clean things up a bit on the way.
There is also a fix of the QoS mapping along with a few workarounds for
hardware / firmware issues that are hard to hit.
Three fixes suggested by static analyzers, and other various stuff.
Most importantly, I update the Copyright note to include the new year."

For the bluetooth bits, Gustavo says:

"More patches to 3.14. The bulk of changes here is the 6LoWPAN support for
Bluetooth LE Devices. The commits that touches net/ieee802154/ are already
acked by David Miller. Other than that we have some RFCOMM fixes and
improvements plus fixes and clean ups all over the tree."

Beyond that, ath9k, brcmfmac, mwifiex, and wil6210 get their usual
level of attention.  The wl1251 driver gets a number of updates,
and there are a handful of other bits here and there.

The recent patch to improve guest receive side flow control (ca2f09f2) had a
slight flaw in the wait condition for the vif thread in that any remaining
skbs in the guest receive side netback internal queue would prevent the
thread from sleeping. An unresponsive frontend can lead to a permanently
non-empty internal queue and thus the thread will spin. In this case the
thread should really sleep until the frontend becomes responsive again.

This patch adds an extra flag to the vif which is set if the shared ring
is full and cleared when skbs are drained into the shared ring. Thus,
if the thread runs, finds the shared ring full and can make no progress the
flag remains set. If the flag remains set then the thread will sleep,
regardless of a non-empty queue, until the next event from the frontend.
