edba17ad85 iwlwifi: remove max_ht_ampdu_exponent config parameter 
This always has the same value, since we don't have any
devices with different values; remove the parameter.

9ce505feb1 iwlwifi: mvm: Check ret code for iwl_mvm_load_nvm_to_nic 
Return value of the iwl_mvm_load_nvm_to_nic func is not analyzed. If load
NVM to nic func fails and NVM is not loaded to fw properly, then fw may
behave badly and lead to some strange issue. This commit will analyze
return value and if load NVM to nic has failed, then the error code is
sent to the previous func, which will trigger WRT log collection.
iwl_fw_dbg_error_collect() func collects dump only if tri type is
FW_DBG_TRIGGER_ALIVE_TIMEOUT. But when Load NVM to nic function fails
trig_type is FW_DBG_TRIGGER_DRIVER. This commit also has code changes to
collect dump when trig_type is FW_DBG_TRIGGER_DRIVER.

8c082a99ed iwlwifi: mvm: simplify iwl_mvm_dbgfs_register 
No need to pass the dbgfs_dir just to assign it to mvm.
Assign to mvm and then call iwl_mvm_dbgfs_register.

This is a preparation towards the addition of a delayed
op_mode_start flow.
This will allow to split the op_mode_start flow.
Registration to debugfs must happen after we register to
mac80211 and the registration to mac80211 will soon be
delayed in certain cases. In order not to have to remember
the debugfs_dir in a separate variable, just set it into
the mvm structure so that it can be usable later.

Declare mvm->debugfs_dir in the iwl_mvm structure even when
IWLWIFI_DEBUGFS isn't enabled to simplify the source code.

21254908cb iwlwifi: mvm: add RFI-M support 
RF Interference Mitigation is a new feature targeted to handle the
problem of interference between DDR memory and WiFi. The role of
the driver is to configure FW with the table holding a mapping
between problematic channels/bands and the corresponding frequencies.

This patch adds RFI infrastructure and adds two debugfs hooks:
- send RFI configuration command (currently with a default table) which
  will reset feature in the FW
- read the table, used by the FW (which can be a subset of the table
  that driver sent).

5a6842455c iwlwifi: mvm: fix the type we use in the PPAG table validity checks 
The value we receive from ACPI is a long long unsigned integer but the
values should be treated as signed char.  When comparing the received
value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison,
so the negative value would actually be treated as a very high number.

To solve this issue, assign the value to our table of s8's before
making the comparison, so the value is already converted when we do
so.

f9a78edb28 iwlwifi: acpi: fix PPAG table sizes 
We were erroneously adding 3 extra values to the table size
calculation, when we should actually add only a 2 (one for the domain
type and one for the enabled/disabled flag).  Fix this for both
revisions we support.

874020f8ad iwlwifi: pcie: don't disable interrupts for reg_lock 
The only thing we do touching the device in hard interrupt context
is, at most, writing an interrupt ACK register, which isn't racing
in with anything protected by the reg_lock.

Thus, avoid disabling interrupts here for potentially long periods
of time, particularly long periods have been observed with dumping
of firmware memory (leading to lockup warnings on some devices.)

403ea939ea iwlwifi: dbg: Mark ucode tlv data as const 
The ucode TLV data may be read-only and should be treated as const
pointers, but currently a few code forcibly cast to the writable
pointer unnecessarily.  This gave developers a wrong impression as if
it can be modified, resulting in crashing regressions already a couple
of times.

This patch adds the const prefix to those cast pointers, so that such
attempt can be caught more easily in future.
