f23caa392a wifi: iwlwifi: mvm: Always allow entering EMLSR from debugfs
EMLSR can't be activated from mac80211. Except for the debugfs, which is
intended for testing purposes. Currently we don't allow entering EMLSR
from debugfs if EMLSR is blocked, i.e. if mvmvif::esr_disable_reason is
not 0. But we need a way to activate EMLSR regardless of the vif being
blocked, for testing. Remove the check of esr_disable_reason

2f33561ea8 wifi: iwlwifi: mvm: trigger link selection after exiting EMLSR
If the reason for exiting EMLSR was a blocking reason, wait for the
corresponding unblocking event:
- if there is an ongoing scan - do nothing. Link selection will be
  triggered at the end of it.
- If more than 30 seconds passed since the exit, trigger MLO scan, which
  will trigger link selection
- If less then 30 seconds passed since exit, reuse the latest link
  selection result

If the reason for exiting EMLSR was an exit reason (IWL_MVM_EXIT_*),
schedule MLO scan in 30 seconds.

72c19df24a wifi: iwlwifi: cleanup EMLSR when BT is active handling
BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the
vif from using EMLSR with a different link pair. In addition, storing it
in mvmvif:disable_esr_reason requires extracting the BT Coex bit before
checking if EMLSR is blocked or not for a specific vif.

Therefore, change the BT Coex bit to be an exit reason and not a
blocker. On link selection, EMLSR mode will be re-calculated for the 2.4
GHz link instead of checking that bit.

While at it, move the relevant function declarations to the EMLSR
functions area in mvm.h

b73c138a87 wifi: iwlwifi: pcie: allocate dummy net_device dynamically
struct net_device shouldn't be embedded into any structure, instead,
the owner should use the priv space to embed their state into net_device.

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].

Un-embed the net_device from struct iwl_trans_pcie by converting it
into a pointer. Then use the leverage alloc_netdev() to allocate the
net_device object at iwl_trans_pcie_alloc.

The private data of net_device becomes a pointer for the struct
iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent
given the net_device object.

On older (pre-MLD API) devices, we started also calling
iwl_mvm_set_link_mapping()/iwl_mvm_unset_link_mapping(),
but of course not also iwl_mvm_remove_link(). Since the

causes us to run out of FW link IDs very quickly. Fix
it by releasing the link ID correctly.

However, ieee80211_set_active_links is called with more than one link in
2 cases:
- After driver's link selection decided to enter EMLSR
- From debugfs, for testing purposes.
For both cases there is no need to recompute all the considerations
determining whether to activate EMLSR.
Instead, only check if the vif is not blocked for EMLSR.

492bc4e49f wifi: iwlwifi: mvm: implement EMLSR prevention mechanism.
Address scenarios where repeated entry and exit from EMLSR occur, such as
encountering missed beacons on a specific link,
while still discovering that link during a scan.

To mitigate this, introduce the EMLSR prevention mechanism, which operates
as follows:
- On each exit from EMLSR event, record the timestamp and the exit
  reason.
- If two consecutive exits happen for the same reason within a
  400-second window, enforce a 300-second EMLSR prevention.
- If a third exit for the same reason occurs within 400 seconds from the
  second exit, enforce an extended EMLSR prevention of 600 seconds.

6cf7df9f01 wifi: iwlwifi: mvm: Add helper functions to update EMLSR status
There are reasons for which we need to exit EMLSR, but not to block it
completely, and there are reasons for which we need to block EMLSR.

For both reason types we have the enum iwl_mvm_esr_state, when the
blocking reasons are stored in the `mvmvif::esr_disable_reason` bitmap.

This change introduces the APIs to use in the different cases:
- iwl_mvm_exit_esr - will exit from EMLSR mode.
- iwl_mvm_block_esr - will update the bitmap and exit EMLSR, to
  be used for the blocking reasons only.
- iwl_mvm_unblock_esr - will update the bitmap. To be used for the
  blocking reasons only.

8c73e8b595 wireless-next patches for v6.10
The first "new features" pull request for v6.10 with changes both in
 stack and in drivers. The big thing in this pull request is that
 wireless subsystem is now almost free of sparse warnings. There's only
 one warning left in ath11k which was introduced in v6.9-rc1 and will
 be fixed via the wireless tree.
 
 Realtek drivers continue to improve, now we have support for RTL8922AE
 and RTL8723CS devices. ath11k also has long waited support for P2P.
 
 This time we have a small conflict in iwlwifi as we didn't consider it
 as major enough to justify merging wireless tree to wireless-next. But
 Stephen has an example merge resolution which should help with fixing
 the conflict:
 
 https://lore.kernel.org/all/20240326100945.765b8caf@canb.auug.org.au/
 
 Major changes:
 
 rtw89
 
 * RTL8922AE Wi-Fi 7 PCI device support
 
 rtw88
 
 * RTL8723CS SDIO device support
 
 iwlwifi
 
 * don't support puncturing in 5 GHz
 
 * support monitor mode on passive channels
 
 * BZ-W device support
 
 * P2P with HE/EHT support
 
 ath11k
 
 * P2P support for QCA6390, WCN6855 and QCA2066
