'destroy_workqueue()' already drains the queue before destroying it, so
there is no need to flush it explicitly.
Remove the redundant 'flush_workqueue()' calls.

Use module_pci_driver for drivers whose init and exit functions
only register and unregister, respectively.

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Send EAPOL frames via control path so they can be treated in a different
way rather than normal data frames. In this case EAPOLs are sent with
higher priority and with disabled aggregation and encryption. Besides,
all devices benefit from sending EAPOL frames via high priority path,
so move the functionality from chip specific to common code.

Rx descriptors queue length is hardware specific. Current common default
value is no more than an accident. So move Rx descriptor queue setup to
platform PCIe backend in the same way as it is already done for Tx.

Instead of using to_pci_dev + pci_get_drvdata,
use dev_get_drvdata to make code simpler.

This patch streamlines firmware state tracking. In particular, state
QTNF_FW_STATE_FW_DNLD_DONE is removed, states QTNF_FW_STATE_RESET and
QTNF_FW_STATE_DETACHED are merged into a single state. Besides, new
state QTNF_FW_STATE_RUNNING is introduced to distinguish between
the following two cases:
- firmware load succeeded, firmware init process is ongoing
- firmware init succeeded, firmware is fully functional

Report that firmware is up and running only for successful firmware
download. Simplify qtnf_pcie_fw_boot_done: modify error path so that
no need to pass firmware dowload result to this function. Finally,
do not create debugfs entries if firmware download succeeded,
but core attach failed.

This patch adds support for QSR1000/QSR2000 family of chipsets
to qtnfmac_pcie platform driver.
QSR1000/QSR2000 (aka Topaz) is a family of 80MHz, 11ac Wave2,
4x4/2x4/2x2 chips, including single and dual band devices.
Depending on specific chip model and firmware in use, either
STA or both STA and AP modes are supported.
Patch adds Topaz support to qtnfmac_pcie driver. Proper platform
bus will be selected on probing based on chip ID.

Command responses and events from the firmware are copied twice in
control path: at first in shm core (qtnf_shm_handle_new_data) and
then in pcie bus drivers (qtnf_pcie_control_rx_callback). There
is no need to copy this data twice, it can be done only once
in rx callbacks.

Waiting for "completion" to be set in FW load thread can not be used
in case PCIe remove is called before FW load work was scheduled.
Just wait for work completion instead to avoid problems.
