After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be
cleared, and another CPU can start napi thread and access per-CQ variable,
cq->work_done. If the other thread (for example, from busy_poll) sets
it to a value >= budget, this thread will continue to run when it should
stop, and cause memory corruption and panic.
To fix this issue, save the per-CQ work_done variable in a local variable
before napi_complete_done(), so it won't be corrupted by a possible
concurrent thread after napi_complete_done().
Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done
variable race is fixed, so the driver is able to reliably support features
like busy_poll.

Refill RX queue in batches of descriptors to improve performance. Refill
is allowed to fail as long as a minimum number of descriptors is active.
Thus, a limited number of failed RX buffer allocations is now allowed
for normal operation. Previously every failed allocation resulted in a
dropped frame.
If the minimum number of active descriptors is reached, then RX buffers
are still reused and frames are dropped. This ensures that the RX queue
never runs empty and always continues to operate.

Without interrupt throttling, iperf server mode generates a CPU load of
100% (A53 1.2GHz). Also the throughput suffers with less than 900Mbit/s
on a 1Gbit/s link. The reason is a high interrupt load with interrupts
every ~20us.
Reduce interrupt load by throttling of interrupts. Interrupt delay
default is 64us. For iperf server mode the CPU load is significantly
reduced to ~20% and the throughput reaches the maximum of 941MBit/s.
Interrupts are generated every ~140us.

The main usage of the struct thunderbolt_ip_frame_header is to handle
the packets on the media layer. The header is bound to the protocol
in which the byte ordering is crucial. However the data type definition
doesn't use that and sparse is unhappy, for example (17 altogether):
.../thunderbolt.c:718:23: warning: cast to restricted __le32
.../thunderbolt.c:966:42: warning: incorrect type in assignment (different base types)
.../thunderbolt.c:966:42: expected unsigned int [usertype] frame_count
.../thunderbolt.c:966:42: got restricted __le32 [usertype]
Switch to the bitwise types in the struct thunderbolt_ip_frame_header to
reduce this, but not completely solving (9 left), because the same data
type is used for Rx header handled locally (in CPU byte order).

Some combinations of hosts cannnot detect mt7921e after reboot. The
interoperability issue is caused by the status mismatch between host
and chip fw. In such cases, the driver should stop chip activities
and reset chip to default state before reboot.

The SPR parameter set comprises OBSS PD threshold for SRG and
non SRG and Bitmap of BSS color and partial BSSID. This adds
support to configure fields of SPR element to firmware.
User can disable firmware SR algorithms by turning sr_scene_detect off.

As comment of pci_get_device() says, it returns a pci_device with its
refcount increased. We need to call pci_dev_put() to decrease the
refcount. Save the return value of pci_get_device() and call
pci_dev_put() to decrease the refcount.
