Rick Farrington ac13d6d8ea liquidio: fix hang when re-binding VF host drv after running DPDK VF driver 
When configuring SLI_PKTn_OUTPUT_CONTROL, VF driver was assuming that IPTR
mode was disabled by reset, which was not true.  Since DPDK driver had
set IPTR mode previously, the VF driver (which uses buf-ptr-only mode) was
not properly handling DROQ packets (i.e. it saw zero-length packets).

This represented an invalid hardware configuration which the driver could
not handle.

Helge Deller 6e85d7a8bc liquidio: Use %pad printk format for dma_addr_t values 
Use the existing %pad printk format to print dma_addr_t values.
This avoids the following warnings when compiling on the parisc platform:

warning: format '%llx' expects argument of type 'long long unsigned int', but argument 2 has type 'dma_addr_t {aka unsigned int}' [-Wformat=]

Rick Farrington 4fed38cf26 liquidio: fix kernel panic when NIC firmware is older than 1.7.2 
Pre-1.7.2 NIC firmware does not support (and does not respond to) the "get
speed" command which is sent by the 1.7.2 driver (for CN23XX-225 cards
only) during modprobe.  Due to a bug in older firmware (with respect to
unknown commands), this unsupported command causes a cascade of errors that
ends in a kernel panic.

Fix it by making the sending of the "get speed" command conditional on the
firmware version.

Nicholas Mc Guire 7481a8576a liquidio: make timeout HZ independent and readable 
schedule_timeout_* takes a timeout in jiffies but the code currently is
passing in a constant which makes this timeout HZ dependent. So define
a constant with (hopefully) meaningful name and pass it through
msecs_to_jiffies() to fix the HZ dependency.

Kees Cook fd7becedb1 treewide: Use array_size() in vzalloc_node() 
The vzalloc_node() function has no 2-factor argument form, so
multiplication factors need to be wrapped in array_size(). This patch
replaces cases of:

        vzalloc_node(a * b, node)

with:
        vzalloc_node(array_size(a, b), node)

as well as handling cases of:

        vzalloc_node(a * b * c, node)

with:

        vzalloc_node(array3_size(a, b, c), node)

This does, however, attempt to ignore constant size factors like:

        vzalloc_node(4 * 1024, node)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

Raghu Vatsavayi ccdd0b4c35 liquidio: prevent rx queues from getting stalled 
This commit has fix for RX traffic issues when we stress test the driver
with continuous ifconfig up/down under very high traffic conditions.

Reason for the issue is that, in existing liquidio_stop function NAPI is
disabled even before actual FW/HW interface is brought down via
send_rx_ctrl_cmd(lio, 0). Between time frame of NAPI disable and actual
interface down in firmware, firmware continuously enqueues rx traffic to
host. When interrupt happens for new packets, host irq handler fails in
scheduling NAPI as the NAPI is already disabled.

After "ifconfig <iface> up", Host re-enables NAPI but cannot schedule it
until it receives another Rx interrupt. Host never receives Rx interrupt as
it never cleared the Rx interrupt it received during interface down
operation. NIC Rx interrupt gets cleared only when Host processes queue and
clears the queue counts. Above anomaly leads to other issues like packet
overflow in FW/HW queues, backpressure.

Fix:
This commit fixes this issue by disabling NAPI only after informing
firmware to stop queueing packets to host via send_rx_ctrl_cmd(lio, 0).
send_rx_ctrl_cmd is not visible in the patch as it is already there in the
code. The DOWN command also waits for any pending packets to be processed
by NAPI so that the deadlock will not occur.

Intiyaz Basha 697fefc7c1 liquidio: Prioritize control messages 
During heavy tx traffic, control messages (sent by liquidio driver to NIC
firmware) sometimes do not get processed in a timely manner.  Reason is:
the low-level metadata of control messages and that of egress network
packets indicate that they have the same priority.

Fix it by setting a higher priority for control messages through the new
ctrl_qpg field in the oct_txpciq struct.  It is the NIC firmware that does
the actual setting of priority by writing to the new ctrl_qpg field; the
host driver treats that value as opaque and just assigns it to pki_ih3->qpg
