lio_enable_irq (called by napi poll) is reporting to Octeon an inaccurate
count of processed rx packets causing Octeon to eventually stop forwarding
packets to the host. Fix it by using this formula for an accurate count:
processed rx packets = droq->pkt_count - droq->pkts_pending
Also increase SOFT_COMMAND_BUFFER_SIZE to match what the firmware expects.

There's a rare pci_driver.probe failure of the VF driver that's caused by
PF/VF handshake going out of sync. The culprit is octeon_mbox_write() who
ignores an ack timeout condition; it just keeps unconditionally writing all
elements of mbox_cmd->data[] even when the other side is not ready for
them. Fix it by making each write of mbox_cmd->data[i] conditional to
having previously received an ack.
Also fix the octeon_mbox_state enum such that each state gets a unique
value. Also add ULL suffix to numeric literals in macro definitions.

When multiple liquidio NICs are plugged in, the first insmod of the PF
driver succeeds. But after an rmmod, a subsequent insmod fails. Reason is
during rmmod, the PF driver resets the Octeon of only one of the NICs; it
neglects to reset the Octeons of the other NICs.
Fix the insmod failure by adding the missing Octeon resets at rmmod. Keep
a per-NIC refcount that indicates the number of active PFs in a given NIC.
When the refcount goes to zero, then reset the Octeon of that NIC.

Driver follows a method of taking one extra reference on the
page for recycling which is fine in usual packet path where
each 64KB page is segmented into multiple receive buffers.
But in XDP mode since there is just one receive buffer per
page taking extra page reference itself becomes big bottleneck
consuming ~50% of CPU cycles due to atomic operations.
This patch adds a internal ref count in pgcache for each
page and additional page references are taken in a batch
instead of just one at a time. Internal i.e 'pgcache->ref_count'
and page's i.e 'page->_refcount' counters are compared to check
page's recyclability.

Since SQ for XDP TX will be used only on a single cpu i.e
SQ description creation and freeing, using atomic free count
is not necessary and will become a bottleneck. Hence added
a separate 'xdp_free_cnt' used for SQs designated for XDP
to track descriptor free count.
Changes also include
- A new entry 'xdp_page' is added to save transmitted packet's
page pointer for later cleanup.
- XDP Tx SQ's doorbell is ringed once per NAPI instance.
- Retrieving designated SQ for packets being sent out by stack

Adds support for page recycling for allocating receive buffers
to reduce cost of refilling RBDR ring. Also got rid of using
compound pages when pagesize is 4K, only order-0 pages now.
Only page is recycled, DMA mappings still needs to be done for
every receive buffer allocated due to following constraints
- Cannot have just one receive buffer per 64KB page.
- There is just one buffer ring shared across 8 Rx queues, so
buffers of same page can go to any Rx queue.
- HW gives buffer address where packet has been DMA'ed and not
the index into buffer ring.
This makes it not possible to resue DMA mapping info. So unfortunately
have to go through costly mapping route for every buffer.

For security reasons, NIC firmware does not allow VF to set its VLAN if PF
set it already. Firmware allows VF to set its VLAN if PF did not set it.
After the VF instructs the firmware to set the VLAN, VF always indicates
(via return 0) that the operation is successful--even for the times when it
isn't.
Put in a mechanism for the VF's set VLAN function to receive the firmware
response code, then make that function return -EPERM if the firmware
forbids the operation.
Make that mechanism available for other functions that may, in the future,
be interested in receiving the response code from the firmware. That
mechanism involves adding new fields to struct octnic_ctrl_pkt, so make all
users of struct octnic_ctrl_pkt initialize the struct to zero before using
it; otherwise, the mechanism might act on uninitialized garbage.

Detection of watchdog timeout of Octeon cores is flawed and susceptible to
false alarms. Refactor by removing the detection code, and in its place,
leverage existing code that monitors for an indication from the NIC
firmware that an Octeon core crashed; expand the meaning of the indication
to "an Octeon core crashed or its watchdog timer expired". Detection of
watchdog timeout is now delegated to an exception handler in the NIC
firmware; this is free of false alarms.
Also if there's an Octeon core crash or watchdog timeout:
(1) Disable VF Ethernet links.
(2) Decrement the module refcount by an amount equal to the number of
active VFs of the NIC whose Octeon core crashed or had a watchdog
timeout. The refcount will continue to reflect the active VFs of
other liquidio NIC(s) (if present) whose Octeon cores are faultless.
Item (2) is needed to avoid the case of not being able to unload the driver
because the module refcount is stuck at some non-zero number. There is
code that, in normal cases, decrements the refcount upon receiving a
message from the firmware that a VF driver was unloaded. But in
exceptional cases like an Octeon core crash or watchdog timeout, arrival of
that particular message from the firmware might be unreliable. That normal
case code is changed to not touch the refcount in the exceptional case to
avoid contention (over the refcount) with the liquidio_watchdog kernel
thread who will carry out item (2).

Change to support host<->firmware command return value.
Fix for vf mac addr state command.
1. Added support for firmware commands to return a value:
- previously, the returned code overlapped with host codes, thus
commands were only returning 0 (success) or -1 (interpreted as
timeout)
- per 'response_manager.h', the error codes are split into two fields
(major/minor) now, firmware commands are grouped into their own
'major' group, separate from the host's 'major' group, which allow f/w
commands to return any 16-bit value
2. The command to set vf mac addr was logging a success message even if
command failed. Now command uses a callback function to log the status
message.
3. The command to set vf mac addr was not logging a message when set via
the host 'ip' command. Now, the callback function will log an

All IRQs owned by the PF and VF drivers share the same nondescript name
"octeon"; this makes it difficult to setup interrupt affinity.
Change the IRQ names to reflect their specific purpose:
LiquidIO<id>-<func>-<type>-<queue pair num>
Examples:
LiquidIO0-pf0-rxtx-3
LiquidIO1-vf1-rxtx-0
LiquidIO0-pf0-aux
We cannot use netdev->name for naming the IRQs because:
1. Early during init, the PF and VF drivers require interrupts to
send/receive control data from the NIC firmware; so the PF and VF
must request IRQs long before the netdev struct is registered.
2. The IRQ name can only be specified at the time it is requested.
It cannot be changed after that.

ACPI support has been added to ARM IOMMU driver in 4.10 kernel
and that has resulted in VNIC interfaces throwing translation
faults when kernel is booted with ACPI as driver was not using
DMA API. This patch fixes the issue by using DMA API which inturn
will create translation tables when IOMMU is enabled.
Also VNIC doesn't have a seperate receive buffer ring per receive
queue, so there is no 1:1 descriptor index matching between CQE_RX
and the index in buffer ring from where a buffer has been used for
DMA'ing. Unlike other NICs, here it's not possible to maintain dma
address to virt address mappings within the driver. This leaves us
no other choice but to use IOMMU's IOVA address conversion API to
get buffer's virtual address which can be given to network stack
for processing.

This patch fixes the case where there is no phydev attached
to a LMAC in DT due to non-existance of a PHY driver or due
to usage of non-stanadard PHY which doesn't support autoneg.
Changes dependeds on firmware to send correct info w.r.t
PHY and autoneg capability.
This patch also covers a case where a 10G/40G interface is used
as a 1G with convertors with Cortina PHY in between.
