net/qede/base: avoid possible race condition

There's a possible race in multiple VF scenarios for base driver users
that use the optional APIs ecore_iov_pf_get_and_clear_pending_events,
ecore_iov_pf_add_pending_events. If the client doesn't synchronize the two
calls, it's possible for the PF to clear a VF pending message indication
without ever getting it [as 'get & clear' isn't atomic], leading to VF
timeout on the command.

The solution is to switch into a per-VF indication rather than having a
bitfield for the various VFs with pending events. As part of the solution,
the setting/clearing of the indications is done internally by base driver.
As a result, ecore_iov_pf_add_pending_events is no longer needed and
ecore_iov_pf_get_and_clear_pending_events loses the 'and_clear' from its
name as its now a proper getter.

A VF would be considered 'pending' [I.e., get_pending_events() should
have '1' for it in its bitfield] beginning with the PF's base driver
recognizing a message sent by that VF [in SP_DPC] and ending only when
that VF message is processed.

This command will report on success and will print ""Flow rule #0 created"
although it should have failed as queue index number 5 does not exist

The second bug occurs when executing in testpmd "port start all" following
a port configuration. Assuming 1 pair of rx and tx queues an error is
reported: "Fail to start port 0"

Before this commit a fixed max number (16) of rx and tx queue pairs were
created on startup where the file descriptors (fds) of rx and tx pairs were
identical.  As a result in the first bug queue index 5 existed because the
tap device was created with 16 rx and tx queue pairs regardless of the
configured number of queues. In the second bug when tap device was started
tx fd was closed before opening it and executing ioctl() on it. However
closing the sole fd of the device caused ioctl to fail with "No such
device".

This commit creates the configured number of rx and tx queue pairs (up to
max 16) and assigns a unique fd to each queue. It was written to solve the

NFP PMD implement now PF and VF drivers. Although the driver
functionality is the same by now, except for initialization, it
will change with future PF additions.

A new feature is required for describing the firmware upload

updated soon in another patch.

SRIOV is not supported by the PF yet, and it is wrong to include it
as a VF driver feature, so none of the files have such a feature.

net/nfp: support PF multiport

A NFP PF PCI device can have several physical ports, up to 8. Because
DPDK core creates one eth_dev per PCI device, nfp pf probe function
is used. Number of PF ports is obtained from firmware symbol using
NSPU API. Inside PF probe function an eth_dev per port is created and
nfp_net_init invoked for each port.

There are some limitations regarding multiport: rx interrupts and
device hotplug are not supported.

Interrupts are handled with the VFIO or UIO drivers help. Those
drivers just know about PCI devices, so it is not possible, without
changing how DPDK handles interrupts, manage interrupts assigned to
different PF ports.

About hotplug, the problem is this functionality is based on a PCI
device, and although device plugin is possible, which would add as
many ports as supported by firmware, unplug is based on device name
linked to a eth_dev, and device name has a suffix now (_portX, with X
being the port index) which DPDK core is not aware of. While rx
interrupts with multiport could be likely solved with some layer of
indirection, hotplug would require changes to DPDK core.
