This change cleans up the i40e/i40evf_set_itr_per_queue function by
dropping all the unneeded pointer chases. Instead we can just pull out the
pointers for the Tx and Rx rings and use them throughout the function.

This patch adds back the capability to turn off offloads when VF has
VLAN set. The commit 0a3b4f702fb1 ("i40evf: enable support for VF VLAN
tag stripping control") adds the i40evf_set_features function and
changes the 'turn off' flow for offloads. This patch adds that
capability back by moving checking the VLAN option for VF to the
next statement.

This patch reorders i40e_add_del_fdir and i40e_update_ethtool_fdir_entry
calls so that we first remove an already existing filter (inside
i40e_update_ethtool_fdir_entry using i40e_add_del_fdir) and then
we add a new one with i40e_add_del_fdir.
After applying this patch, creating multiple identical filters (with
the same location) one after another doesn't revert their behavior
but behaves correctly.

We can now transmit SKBs in 2 ways:
1. Via the MC (for the 7XXX series and earlier), using
efx_ptp_xmit_skb_mc().
2. Via the TX queues on the dedicated PTP channel (8XXX series and later),
using efx_ptp_xmit_skb_queue().
The PTP worker thread uses the method set up at probe time. It never
checked the return code from the old efx_ptp_xmit_skb(), so it now
returns void.
We increment the TX dropped counter of the device if the transmit fails.
As a result of the probe per channel the remove gets called multiple times.
Clean up efx->ptp_data properly to avoid the 2nd call blowing up.

Before this work, TX timestamping is done by sending each SKB to the MC.
On the 8000 series (Medford1) we have high speed timestamping via the
MAC, which means we can use normal TX queues for this without a
significant drop in bandwidth. On the X2000 series (Medford2) support
for transmitting via the MC is removed, so the new way must be used.
This patch enables timestamping on a TX queue, if requested.
It also enhances TX event handling to process the extra completion events,
and puts the time in the SKB.

STA control register has areas of mode and opcodes for opeations. 18 bit is
using for mode selection, where 0 is old MIO/MDIO access method and 1 is
indirect access mode. 19-20 bits are using for setting up read/write
operation(STA opcodes). In current state 'read' is set into old MIO/MDIO mode
with 19 bit and write operation is set into 18 bit which is mode selection,
not a write operation. To correlate write with read we set it into 20 bit.
All those bit operations are MSB 0 based.

100GbE Intel Wired LAN Driver Updates 2018-01-24
This series contains updates to fm10k only.
Alex fixes MACVLAN offload for fm10k, where we were not seeing unicast
packets being received because we did not correctly configure the
default VLAN ID for the port and defaulting to 0.
Jake cleans up unnecessary parenthesis in a couple of "if" statements.
Fixed the driver to stop adding VLAN 0 into the VLAN table, since it
would cause the VLAN table to be inconsistent between the PF and VF.
Also fixed an issue where we were assuming that VLAN 1 is enabled when
the default VLAN ID is not set, so resolve by not requesting any filters
for the default_vid if it has not yet been assigned.
Ngai fixes an issue which was generating a dmesg regarding unbale to
kill a particular VLAN ID for the device. This is due to
ndo_vlan_rx_kill_vid() exits with an error and the handler for this ndo
is fm10k_update_vid() which exits prematurely under PF VLAN management.
So to resolve, we must check the VLAN update action type before exiting
fm10k_update_vid(), and act appropriately based on the action type.
Also corrected code comment typos.

Since commit 856dfd69e84f ("fm10k: Fix multicast mode synch issues",
2016-03-03) we've incorrectly assumed that VLAN 1 is enabled when the
default VID is not set.
This occurs because we check the default_vid and if it's zero, start
several loops over the active_vlans bitmask at 1, instead of checking to
ensure that that bit is active.
This happened because of commit d9ff3ee8efe9 ("fm10k: Add support for
VLAN 0 w/o default VLAN", 2014-08-07) which mistakenly assumed that we
should send requests for MAC and VLAN filters with VLAN 0 when the
default_vid isn't set.
However, the switch generally considers this an invalid configuration,
so the only time we'd have a default_vid of 0 is when the switch is
down.
Instead, lets just not request any filters for the default_vid if it's
not yet been assigned.

Currently, when the driver loads, it sends a request to add VLAN 0 to the
VLAN table. For the PF, this is honored, and VLAN 0 is indeed set. For
the VF, this request is silently converted into a request for the
default VLAN as defined by either the switch vid or the PF vid.
This results in the odd behavior that the VLAN table doesn't appear
consistent between the PF and the VF.
Furthermore, setting a MAC filter with VLAN 0 is generally considered an
invalid configuration by the switch, and since commit 856dfd69e84f
("fm10k: Fix multicast mode synch issues", 2016-03-03) we've had code
which prevents us from ever sending such a request.
Since there's not really a good reason to keep VLAN 0 in the VLAN table,
stop requesting it in fm10k_restore_rx_state().
This might seem to indicate that we would no longer properly configure
the MAC and VLAN tables for the default vid. However, due to the way
that fm10k_find_next_vlan() behaves, it will always return the
default_vid as enabled.

When a VF is under PF VLAN assignment:
ip link set <pf> vf <#> vlan <vid>
This will remove all previous entries in the VLAN table including those
generated by VLAN interfaces created on the VF. The issue arises when
the VF is under PF VLAN assignment and one or more of these VLAN
interfaces of the VF are deleted. When deleting these VLAN interfaces,
the following message will be generated in "dmesg":
failed to kill vid 0081/<vid> for device <vf>
This is due to the fact that "ndo_vlan_rx_kill_vid" exits with an error.
The handler for this ndo is "fm10k_update_vid". Any calls to this
function while under PF VLAN management will exit prematurely and, thus,
it will generate the failure message.
Additionally, since "fm10k_update_vid" exits prematurely, none of the
VLAN update is performed. So, even though the actual VLAN interfaces of
the VF will be deleted, the active_vlans bitmask is not cleared. When
the VF is no longer under PF VLAN assignment, the driver mistakenly
restores the previous entries of the VLAN table based on an
unsynchronized list of active VLANs.
The solution to this issue involves checking the VLAN update action type
before exiting "fm10k_update_vid". If the VLAN update action type is to
"add", this action will not be permitted while the VF is under PF VLAN
assignment and the VLAN update is abandoned like before.
However, if the VLAN update action type is to "kill", then we need to
also clear the active_vlans bitmask. However, we don't need to actually
queue any messages to the PF, because the MAC and VLAN tables have
already been cleared, and the PF would silently ignore these requests
anyways.

The fm10k driver didn't work correctly when macvlan offload was enabled.
Specifically what would occur is that we would see no unicast packets being
received. This was traced down to us not correctly configuring the default
VLAN ID for the port and defaulting to 0.
To correct this we either use the default ID provided by the switch or
simply use 1. With that we are able to pass and receive traffic without any
issues.
In addition we were not repopulating the filter table following a reset. To
correct that I have added a bit of code to fm10k_restore_rx_state that will
repopulate the Rx filter configuration for the macvlan interfaces.

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.

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.
