Doing a bitwise AND between a bool and an int is generally not a good idea.
The bool will be promoted to an int with value 0 or 1,
the int is generally regarded as true with a non-zero value,
thus ANDing them has the potential to yield an undesired result.

1GbE Intel Wired LAN Driver Updates 2018-01-24

This series contains updates to igb and e1000e only.

Corinna Vinschen implements the ability to set the VF MAC to
00:00:00:00:00:00 via RTM_SETLINK on the PF, to prevent receiving
"invlaid argument" when libvirt attempts to restore the MAC address back
to its original state of 00:00:00:00:00:00.

Zhang Shengju adds a new function igb_get_max_rss_queues() to get the
maxium number of RSS queues and to reduce code duplication.

Matt fixes an issue with e1000e where when setting HTHREST, we should
only be setting bit 8.  Also added a dev_info() message to alert when
C-states have been disabled, to help in debugging.

Jesus adds code comments to clarify the idlescope configuration
constraints.

Lyude Paul fixes a kernel crash on hotplug of igb, by checking to ensure
that we are in the process of dismantling the netdev on hotplug events.

Markus Elfring removes a duplicate message for a memory allocation
failure.

Daniel Hua fixes an issue where transmit timestamps will stop being put
into the socket when link is repeatedly up/down due to TSYNCTXCTL's TXTT
bit (Transmit timestamp valid bit) not clearing in the timeout logic of
ptp_tx_work(), which in turn causes no new timestamp to be loaded to the
TXSTMP register.

net: sched: propagate extack to cls offloads on destroy and only with skip_sw

This series some of Jiri's comments and the fact that today drivers
may produce extack even if there is no skip_sw flag (meaning the
driver failure is not really a problem), and warning messages will
only confuse the users.

First patch propagates extack to destroy as requested by Jiri, extack
is then propagated to the driver callback for each classifier.  I chose
not to provide the extack on error paths.  As a rule of thumb it seems
best to keep the extack of the condition which caused the error.  E.g.

     err = this_will_fail(arg, extack);
     if (err) {
        undo_things(arg, NULL /* don't pass extack */);
	return err;
     }

Note that NL_SET_ERR_MSG() will ignore the message if extack is NULL.
I was pondering whether we should make NL_SET_ERR_MSG() refuse to
overwrite the msg, but there seem to be cases in the tree where extack
is set like this:

     err = this_will_fail(arg, extack);
     if (err) {
        undo_things(arg, NULL /* don't pass extack */);
	NL_SET_ERR_MSG(extack, "extack is set after undo call :/");
	return err;
     }

I think not passing extack to undo calls is reasonable.

Problem description:
After ethernet cable connect and disconnect for several iterations on a
device with i210, tx timestamp will stop being put into the socket.

Steps to reproduce:
1. Setup a device with i210 and wire it to a 802.1AS capable switch (
Extreme Networks Summit x440 is used in our case)
2. Have the gptp daemon running on the device and make sure it is synced
with the switch
3. Have the switch disable and enable the port, wait for the device gets
resynced with the switch
4. Iterates step 3 until the device is not albe to get resynced
5. Review the log in dmesg and you will see warning message "igb : clearing
Tx timestamp hang"

Root cause:
If ptp_tx_work() gets scheduled just before the port gets disabled, a LINK
DOWN event will be processed before ptp_tx_work(), which may cause timeout
in ptp_tx_work(). In the timeout logic, the TSYNCTXCTL's TXTT bit (Transmit
timestamp valid bit) is not cleared, causing no new timestamp loaded to
TXSTMP register. Consequently therefore, no new interrupt is triggerred by
TSICR.TXTS bit and no more Tx timestamp send to the socket.

As it turns out, normally the freeing of IRQs that would fix this is called
inside of the scope of __igb_close(). However, since the device is
already gone by the point we try to unregister the netdevice from the
driver due to a hotplug we end up seeing that the netif isn't present
and thus, forget to free any of the device IRQs.

So: make sure that if we're in the process of dismantling the netdev, we
always allow __igb_close() to be called so that IRQs may be freed
normally. Additionally, only allow igb_close() to be called from
__igb_close() if it hasn't already been called for the given adapter.

Before libvirt modifies the MAC address and vlan tag for an SRIOV VF
for use by a virtual machine (either using vfio device assignment or
macvtap passthru mode), it saves the current MAC address and vlan tag
so that it can reset them to their original value when the guest is
done.  Libvirt can't leave the VF MAC set to the value used by the
now-defunct guest since it may be started again later using a
different VF, but it certainly shouldn't just pick any random value,
either. So it saves the state of everything prior to using the VF, and
resets it to that.

The igb driver initializes the MAC addresses of all VFs to
00:00:00:00:00:00, and reports that when asked (via an RTM_GETLINK
netlink message, also visible in the list of VFs in the output of "ip
link show"). But when libvirt attempts to restore the MAC address back
to 00:00:00:00:00:00 (using an RTM_SETLINK netlink message) the kernel
responds with "Invalid argument".

Forbidding a reset back to the original value leaves the VF MAC at the
value set for the now-defunct virtual machine. Especially on a system
with NetworkManager enabled, this has very bad consequences, since
NetworkManager forces all interfacess to be IFF_UP all the time - if
the same virtual machine is restarted using a different VF (or even on
a different host), there will be multiple interfaces watching for
traffic with the same MAC address.

To allow libvirt to revert to the original state, we need a way to
remove the administrative set MAC on a VF, to allow normal host
operation again, and to reset/overwrite the VF MAC via VF netdev.

This patch implements the outlined scenario by allowing to set the
VF MAC to 00:00:00:00:00:00 via RTM_SETLINK on the PF.
igb_ndo_set_vf_mac resets the IGB_VF_FLAG_PF_SET_MAC flag to 0,
so it's possible to reset the VF MAC back to the original value via
the VF netdev.

Note: Recent patches to libvirt allow for a workaround if the NIC
isn't capable of resetting the administrative MAC back to all 0, but
in theory the NIC should allow resetting the MAC in the first place.

Work requests are needed for every ib_post_send(), among them the
ib_post_send() to signal closing. If an smc socket program is cancelled,
the smc connections should be cleaned up, and require sending of closing
signals to the peer. This may fail, if a wait for
a free work request is needed, but is cancelled immediately due to the
cancel interrupt. To guarantee notification of the peer, the wait for
a work request is changed to uninterruptible.

And the area to receive work request completion info with
ib_poll_cq() is cleared first.
And _tx_ variable names are used in the _tx_routines for the
demultiplexing common type in the header.

There is no need to wait for confirmation of pending tx requests
for a closing connection, since pending tx slots are dismissed
when finishing a connection.
