2018-10-08iwlwifi: mvm: use fast balance scan in case of DCM mode with P2P GOAyala Beker
Currently in case of DCM with P2P GO where BSS DTIM interval < 220 msec the fw fails to allocate events for the P2P GO dtim due to long passive scan events. Fix this by requesting all scans in this scenario to be fragmented with fast balance scan time settings. The only exception is in case fragmented scan was planned to be set due to low latency or high throughput reason, set the scan timing as planned.

2018-10-08iwlwifi: mvm: introduce a new fragmented scan type: fast balanceAyala Beker
Fast balance scan is similar to SCAN_TYPE_MILD, but this scan is fragmented and has shorter out of operating channel time, and therefore better match low latency scenarios. Signed-off-by: Ayala Beker <ayala.beker@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

Introduce and use iwl_mvm_cdb_scan_api(), which checks the family. Most of this will go away once the 22000 firmware supports adaptive dwell, after which the V6 scan API won't be used, but the V3 scan *config* API will still need to be distinguished.

2017-11-15iwlwifi: mvm: support version 7 of the SCAN_REQ_UMAC FW commandLuca Coelho
Newer firmware versions (such as iwlwifi-8000C-34.ucode) have introduced an API change in the SCAN_REQ_UMAC command that is not backwards compatible. The driver needs to detect and use the new API format when the firmware reports it, otherwise the scan command will not work properly, causing a command timeout. Fix this by adding a TLV that tells the driver that the new API is in use and use the correct structures for it.

The firmware doesn't send match found notifications when no matchsets are passed. This makes sense because if there are no matchsets, nothing can be matched.
