netvsc_vf_xmit() / dev_queue_xmit() will call VF NIC’s ndo_select_queue

Currently the driver reads RX and TX subCRQ handle array directly from
a DMA-mapped buffer address when it needs to make a H_SEND_SUBCRQ
hcall. This patch stores that information in the ibmvnic_sub_crq_queue
structure instead of reading from the buffer received at login. The
overall goal of this patch is to parse relevant information from the
login response buffer and store it in the driver's private data
structures so that we don't need to read directly from the buffer and
can then free up that memory.

The ena_del_napi_in_range() function unregisters the napi handler for
rings in a given range.
This function had the following WARN_ON macro:
WARN_ON(ENA_IS_XDP_INDEX(adapter, i) &&
adapter->ena_napi[i].xdp_ring);
This macro prints the call stack if the expression inside of it is
true [1], but the expression inside of it is the wanted situation.
The expression checks whether the ring has an XDP queue and its index
corresponds to a XDP one.
This patch changes the expression to
!ENA_IS_XDP_INDEX(adapter, i) && adapter->ena_napi[i].xdp_ring
which indicates an unwanted situation.
Also, change the structure of the function. The napi handler is
unregistered for all rings, and so there's no need to check whether the
index is an XDP index or not. By removing this check the code becomes
much more readable.

The reset work is scheduled by the timer routine whenever it
detects that a device reset is required (e.g. when a keep_alive signal
is missing).
When releasing device resources in ena_destroy_device() the driver
cancels the scheduling of the timer routine without destroying the reset
work explicitly.
This creates the following bug:
The driver is suspended and the ena_suspend() function is called
-> This function calls ena_destroy_device() to free the net device
resources
-> The driver waits for the timer routine to finish
its execution and then cancels it, thus preventing from it
to be called again.
If, in its final execution, the timer routine schedules a reset,
the reset routine might be called afterwards,and a redundant call to
ena_restore_device() would be made.
By changing the reset routine we allow it to read the device's state
accurately.
This is achieved by checking whether ENA_FLAG_TRIGGER_RESET flag is set
before resetting the device and making both the destruction function and
the flag check are under rtnl lock.
The ENA_FLAG_TRIGGER_RESET is cleared at the end of the destruction
routine. Also surround the flag check with 'likely' because
we expect that the reset routine would be called only when
ENA_FLAG_TRIGGER_RESET flag is set.
The destruction of the timer and reset services in __ena_shutoff() have to
stay, even though the timer routine is destroyed in ena_destroy_device().
This is to avoid a case in which the reset routine is scheduled after
free_netdev() in __ena_shutoff(), which would create an access to freed
memory in adapter->flags.

After making use of the gro_flush_timeout attribute I once got a
tx timeout due to an interrupt that wasn't handled. Seems using
irq_enabled can be racy, and it's not needed any longer anyway,
so remove it. I've never seen a report about such a race before,
therefore treat the change as an improvement.
There's just one small drawback: If a legacy PCI interrupt is used,
and if this interrupt is shared with a device with high interrupt
rate, then we may handle interrupts even if NAPI disabled them,
and we may see a certain performance decrease under high network load.

When the ARP monitor is used for link detection, ARP replies are
validated for all slaves (arp_validate=3) and fail_over_mac is set to
active, two slaves of an active-backup bond may get stuck in a state
where both of them are active and pass packets that they receive to
the bond. This state makes IPv6 duplicate address detection fail. The
state is reached thus:
1. The current active slave goes down because the ARP target
is not reachable.
2. The current ARP slave is chosen and made active.
3. A new slave is enslaved. This new slave becomes the current active
slave and can reach the ARP target.
As a result, the current ARP slave stays active after the enslave
action has finished and the log is littered with "PROBE BAD" messages:
> bond0: PROBE: c_arp ens10 && cas ens11 BAD
The workaround is to remove the slave with "going back" status from
the bond and re-enslave it. This issue was encountered when DPDK PMD
interfaces were being enslaved to an active-backup bond.
I would be possible to fix the issue in bond_enslave() or
bond_change_active_slave() but the ARP monitor was fixed instead to
keep most of the actions changing the current ARP slave in the ARP
monitor code. The current ARP slave is set as inactive and backup
during the commit phase. A new state, BOND_LINK_FAIL, has been
introduced for slaves in the context of the ARP monitor. This allows
administrators to see how slaves are rotated for sending ARP requests
and attempts are made to find a new active slave.

tightens the validation of these MAC addresses to match the validation

When we tear down a network namespace, we unregister all
the netdevices within it. So we may queue a slave device
and a bonding device together in the same unregister queue.
If the only slave device is non-ethernet, it would
automatically unregister the bonding device as well. Thus,
we may end up unregistering the bonding device twice.
Workaround this special case by checking reg_state.

While we're at it, remove some code which has never been invoked.
Keep the comment though, as it seems potentially half useful.

The variable 'smt_pdef' is only used if LITTLE_ENDIAN is set, so only
define it if this is the case.
