rtw88: add napi support
Use napi to reduce overhead on rx interrupts.
Driver used to interrupt kernel for every Rx packet, this could
affect both system and network performance. NAPI is a mechanism that
uses polling when processing huge amount of traffic, by doing this
the number of interrupts can be decreased.
Network performance can also benefit from this patch. Since TCP
connection is bidirectional and acks are required for every several
packets. These ack packets occupie the PCI bus bandwidth and could
lead to performance degradation.
When napi is used, GRO receive is enabled by default in the mac80211
stack. So mac80211 won't pass every RX TCP packets to the kernel TCP
network stack immediately. Instead an aggregated large length TCP packet
will be delivered.
This reduces the tx acks sent and gains rx performance. After the patch,
the Rx throughput increases about 25Mbps in 11ac.

iwlwifi: remove incorrect comment in pnvm
We use this driver as a backport that also runs on older kernels (as
part of the backports project). So we use some checks to backport or
prevent code from compiling in incompatible kernel version.
When I took one of the PNVM patches from the backport, I accidentally
left the comment that a certain part of the code doesn't work in older
kernels. This obviously should never be valid for the mainline.

Currently, for all devices and families, failing getting the temp
from the fw is indicated in the log as ERR.
This is too severe for two reasons:
1. The driver has a fall back - and schedules the next temp
read immediately after failing to read temp from the fw.
2. The temp read implementation in the fw is different between
HWs, and on older devices the flow is a-sync and may timeout.

In the carl9170_cmd structure, multiple members that have an explicit
alignment requirement of four bytes are added into a union with explicit
byte alignment, but this in turn is part of a structure that also has
four-byte alignment.
In the wlan.h header, multiple structures contain a ieee80211_hdr member
that is required to be two-byte aligned to avoid alignmnet faults when
processing network headers, but all members are forced to be byte-aligned
using the __packed tag at the end of the struct definition.
In both cases, leaving out the packing does not change the internal
layout of the structure but changes the alignment constraint of the
structure itself.
Change all affected structures to only apply packing where it does
not violate the alignment requirement of the contained structure.

rtlwifi: use tasklet_setup to initialize rx_work_tasklet
In commit
d3ccc14dfe95 most of the tasklets in this driver was
updated to the new API. However for the rx_work_tasklet only the
type of the callback was changed from
void _rtl_rx_work(unsigned long data)
to
void _rtl_rx_work(struct tasklet_struct *t).
The initialization of rx_work_tasklet was still open-coded and the
function pointer just cast into the old type, and hence nothing sets
rx_work_tasklet.use_callback = true and the callback was still called as
t->func(t->data);
with uninitialized/zero t->data.
Commit
6b8c7574a5f8 changed the casting of _rtl_rx_work a bit and
initialized t->data to a pointer to the tasklet cast to an unsigned
long.
This way calling t->func(t->data) might actually work through all the
casting, but it still doesn't update the code to use the new tasklet
API.
Let's use the new tasklet_setup to initialize rx_work_tasklet properly
and set rx_work_tasklet.use_callback = true so that the callback is
called as
t->callback(t);
without all the casting.
