2020-05-08iwlwifi: mvm: add IML/ROM information to the assertion dumpsLuca Coelho
Dump the IML/ROM error code and data, which are read from some registers, when printing an assertion dump. This makes it easier to debug IML/ROM errors.

2020-05-08iwlwifi: mvm: initialize iwl_dev_tx_power_cmd to zeroLuca Coelho
If the REDUCE_TX_POWER_CMD version is v4 or v5, we are not initializing some values before sending to the FW, which causes SAR not to work properly. Solve this by initializing the struct in the declaration.

2020-05-08iwlwifi: mvm: set properly station flags in STA_HE_CTXT_CMDShaul Triebitz
For ACK_ENABLED and 32BIT_BA_BITMAP flags check the station capabilities rather than bss_conf.ack_enabled and bss_conf.multi_sta_back_32bit. These fields are stations capabilities and should not be in bss_conf. Also note that the bss_conf flags are set in station mode only.

2020-04-24mac80211: implement Operating Mode Notification extended NSS supportJohannes Berg
Somehow we missed this for a long time, but similar to the extended NSS support in VHT capabilities, we need to have this in Operating Mode notification. Implement it by * parsing the 160/80+80 bit there and setting the bandwidth appropriately * having callers of ieee80211_get_vht_max_nss() pass in the current max NSS value as received in the operating mode notification in order to modify it appropriately depending on the extended NSS bits. This updates all drivers that use it, i.e. only iwlwifi/mvm.

2020-04-24mac80211: populate debugfs only after cfg80211 initJohannes Berg
When fixing the initialization race, we neglected to account for the fact that debugfs is initialized in wiphy_register(), and some debugfs things went missing (or rather were rerooted to the global debugfs root). Fix this by adding debugfs entries only after wiphy_register(). This requires some changes in the rate control code since it currently adds debugfs at alloc time, which can no longer be done after the reordering.

2020-04-21iwlwifi: fix WGDS check when WRDS is disabledLuca Coelho
In the reference BIOS implementation, WRDS can be disabled without disabling WGDS. And this happens in most cases where WRDS is disabled, causing the WGDS without WRDS check and issue an error. To avoid this issue, we change the check so that we only considered it an error if the WRDS entry doesn't exist. If the entry (or the selected profile is disabled for any other reason), we just silently ignore WGDS.

2020-04-21iwlwifi: mvm: fix inactive TID removal return value usageJohannes Berg
The function iwl_mvm_remove_inactive_tids() returns bool, so we should just check "if (ret)", not "if (ret >= 0)" (which would do nothing useful here). We obviously therefore cannot use the return value of the function for the free_queue, we need to use the queue (i) we're currently dealing with instead.

2020-04-21iwlwifi: mvm: limit maximum queue appropriatelyJohannes Berg
Due to some hardware issues, queue 31 isn't usable on devices that have 32 queues (7000, 8000, 9000 families), which is correctly reflected in the configuration and TX queue initialization. However, the firmware API and queue allocation code assumes that there are 32 queues, and if something actually attempts to use #31 this leads to a NULL-pointer dereference since it's not allocated. Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also add some code to catch this earlier in the future, if the configuration changes perhaps.
