efdbfa0ad0 iwlwifi: fix LED dependencies
The dependencies for LED configuration are highly inconsistent and too
complicated at the moment. One of the results is a randconfig failure I
get very rarely when LEDS_CLASS is in a loadable module, but the wireless
core is built-in:

WARNING: unmet direct dependencies detected for MAC80211_LEDS
  Depends on [n]: NET [=y] && WIRELESS [=y] && MAC80211 [=y] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=MAC80211 [=y])
  Selected by [m]:
  - IWLEGACY [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y]
  - IWLWIFI_LEDS [=y] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y] && IWLWIFI [=m] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=IWLWIFI [=m]) && (IWLMVM [=m] || IWLDVM [=m])

aarch64-linux-ld: drivers/net/wireless/ath/ath5k/led.o: in function `ath5k_register_led':
led.c:(.text+0x60): undefined reference to `led_classdev_register_ext'
aarch64-linux-ld: drivers/net/wireless/ath/ath5k/led.o: in function `ath5k_unregister_leds':
led.c:(.text+0x200): undefined reference to `led_classdev_unregister'

For iwlwifi, the dependency is wrong, since this config prevents the
MAC80211_LEDS code from being part of a built-in MAC80211 driver.

For iwlegacy, this is worse because the driver tries to force-enable
the other subsystems, which is both a layering violation and a bug
because it will still fail with MAC80211=y and IWLEGACY=m, leading
to LEDS_CLASS being a module as well.

The actual link failure in the ath5k driver is a result of MAC80211_LEDS
being enabled but not usable. With the Kconfig logic fixed in the
Intel drivers, the ath5k driver works as expected again.

977df8bd58 iwlwifi: work around reverse dependency on MEI
If the iwlmei code is a loadable module, the main iwlwifi driver
cannot be built-in:

x86_64-linux-ld: drivers/net/wireless/intel/iwlwifi/pcie/trans.o: in function `iwl_pcie_prepare_card_hw':
trans.c:(.text+0x4158): undefined reference to `iwl_mei_is_connected'

Unfortunately, Kconfig enforces the opposite, forcing the MEI driver to
not be built-in if iwlwifi is a module.

To work around this, decouple iwlmei from iwlwifi and add the
dependency in the other direction.

When scheduling a session protection the id is saved but

55c6d8f89d iwlwifi: support 4-bits in MAC step value
We have a MAC component (which is inside the SoC) and it has several
different HW steps.  3 bits used to be enough but now we need 4-bits
to represent all the different steps.

Properly support 4-bits in the MAC step value by refactoring all the
current handling of the MAC step/dash.

Already from family 8000 and up the dash (bits 0-1) no longer exists
and the step (until 8000 bits 2-3) consists of the dash bits as well.

To do this remove the CSR_HW_REV_STEP and the CSR_HW_REV_DASH
macros, replace them with CSR_HW_REV_STEP_DASH and add hw_rev_step
into the trans struct.

In addition remove the CSR_HW_IF_CONFIG_REG_MSK_MAC_STEP and
CSR_HW_IF_CONFIG_REG_MSK_MAC_DASH macros and create a new macro
combining the 2 (this way we don't need shifting or anything else.)

db66abeea3 iwlwifi: mvm: synchronize with FW after multicast commands
If userspace installs a lot of multicast groups very quickly, then
we may run out of command queue space as we send the updates in an
asynchronous fashion (due to locking concerns), and the CPU can
create them faster than the firmware can process them. This is true
even when mac80211 has a work struct that gets scheduled.

Fix this by synchronizing with the firmware after sending all those
commands - outside of the iteration we can send a synchronous echo
command that just has the effect of the CPU waiting for the prior
asynchronous commands to finish. This also will cause fewer of the
commands to be sent to the firmware overall, because the work will
only run once when rescheduled multiple times while it's running.

2438d43086 iwlwifi: mvm: fix delBA vs. NSSN queue sync race
If we happen to decide an NSSN queue sync (IWL_MVM_RXQ_NSSN_SYNC)
for some remaining packets that are still on the queue, but just
after we've decided to do a delBA (which causes its own queues
sync with IWL_MVM_RXQ_NOTIF_DEL_BA) we can end up with a sequence
of events like this:

 CPU 1                              CPU 2

remove BA session with baid N
send IWL_MVM_RXQ_NOTIF_DEL_BA
send IWL_MVM_RXQ_NSSN_SYNC
get IWL_MVM_RXQ_NOTIF_DEL_BA
                                    get IWL_MVM_RXQ_NOTIF_DEL_BA
get IWL_MVM_RXQ_NSSN_SYNC
complete IWL_MVM_RXQ_NOTIF_DEL_BA
remove N from baid_map[]
                                    get IWL_MVM_RXQ_NSSN_SYNC
                                    WARN_ON(!baid_map[N])

Thus, there's a race that leads in hitting the WARN_ON, but more
importantly, it's a race that potentially even results in a new
aggregation session getting assigned to baid N.

To fix this, remove the WARN_ON() in the NSSN_SYNC case, we can't
completely protect against hitting this case, so we shouldn't be
warning. However, guard ourselves against BAID reuse by doing yet
another round of queue synchronization after the entry is removed
from the baid_map, so that it cannot be reused with any in-flight
IWL_MVM_RXQ_NSSN_SYNC messages.
