2018-05-30iwlwifi: mvm: remove division by size of sizeof(struct ieee80211_wmm_rule)Colin Ian King
The subtraction of two struct ieee80211_wmm_rule pointers leaves a result that is automatically scaled down by the size of the size of pointed-to type, hence the division by sizeof(struct ieee80211_wmm_rule) is bogus and should be removed.

To fix a conflict reported by Stephen Rothwell <sfr@canb.auug.org.au>: Today's linux-next merge of the wireless-drivers-next tree got a conflict in: drivers/net/wireless/intel/iwlwifi/iwl-nvm-parse.c between commit: 77e30e10ee28 ("iwlwifi: mvm: query regdb for wmm rule if needed") from the wireless-drivers tree and commits: 9c4f7d512740 ("iwlwifi: move all NVM parsing code to the common files") 4c625c564ba2 ("iwlwifi: get rid of fw/nvm.c") from the wireless-drivers-next tree.

Since our device is regulatory self managed it maintains its regulatory rules by its own.

2017-10-06iwlwifi: acpi: move function to get mcc into acpi codeLuca Coelho
The iwl_get_bios_mcc() function was in the iwl-nvm-parse.c file, but it has nothing to do with the NVM. Move it to fw/acpi.c and rename it to iwl_acpi_get_mcc(). Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-10-06iwlwifi: acpi: add common code to read from ACPILuca Coelho
There are many places where the same process of invoking a method from ACPI is used, causing a lot of duplicate code. To improve this, introduce a new function to get an ACPI object by invoking an ACPI method that can be reused. Additionally, since this function needs to be called when we only have the trans, the opmode or the device, introduce a new debug macro that gets the device as a parameter so it can be used in the new function.

2017-10-06iwlwifi: nvm-parse: unify channel flags printingJohannes Berg
The current channel flags printing is very strange and messy, in LAR we sometimes print the channel number and sometimes the frequency, in both we print a calculated value (whether ad-hoc is supported or not) etc. Unify all this to * print the channel number, not the frequency * remove the band print (2.4/5.2 GHz, it's obvious) * remove the calculated Ad-Hoc print Doing all of this also gets the length of the string to a max of 101 characters, which is below the max of 110 for tracing, and thus avoids the warning that came up on certain channels with certain flag combinations.

2017-08-18iwlwifi: use big-endian for the hw section of the nvmLuca Coelho
Unlike the other sections of the NVM, the hw section is in big-endian. To read a value from it, we had to cast it to __be16. Fix that by using __be16 * for the entire section. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-08-18iwlwifi: add workaround to disable wide channels in 5GHzLuca Coelho
The OTP in some SKUs have erroneously allowed 40MHz and 80MHz channels in the 5.2GHz band. The firmware has been modified to not allow this in those SKUs, so the driver needs to do the same otherwise the firmware will assert when we try to use it.

2017-08-18iwlwifi: update channel flags parserLuca Coelho
There are some new flags in the channel flags that we don't know about. Also, the "WIDE" flag is very confusing, because it actually means 20MHz bandwidth, which is not very wide. Add the new flags and rename the confusing one. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-08-01iwlwifi: split the regulatory rules when the bandwidth flags require itEmmanuel Grumbach
When we create a regulatory domain out of an MCC notification, we need to make sure that all the channels in the rule have the exact same properties. The current code mixes channel 36 and 40 although 36 can be a control channel with HT40+ (36, 40) whereas 40 can't be a control channel with HT40+ since (40, 44) is invalid. Because of that, cfg80211 would allow to connect in 40MHz to APs that are configured to channel 40 HT40+ and that made our firmware assert. Fix this by checking the bandwidth flags before taking the decision if the rule should be split. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299 partly.

2016-09-19iwlwifi: check for valid ethernet address provided by OEMHaim Dreyfuss
In 9000 family products we added an option to let the OEM fuse the mac address via registers. If these registers are zeroed we use the OTP address instead.

2016-07-01iwlwifi: advertise maximal MPDU length when Rx MQ is supportedEmmanuel Grumbach
The new hardware that supports multiple queue also de-aggregates A-MSDUs. This means that we can advertise the maximal size of A-MSDUs regardless of the receive buffer's size. In order to be able to forcefully use a lower A-MSDU size, add a default value for the module parameter. Pre-9000 will have a default of 4K, and 9000 will have 12K. Setting the amsdu_size module parameter to 4K will limit the A-MSDU on 9000 as well.

2016-05-10iwlwifi: consider VHT 160MHz while parsing NVMGregory Greenman
Devices belonging to 9000 family can support VHT 160MHz channel width, so need to consider it when configuring VHT capabilities. However, NVM file doesn't have a single bit specifying that 160MHz is supported. This patch turns on 160MHz support in VHT capabilities in case there's at least one channel supporting 160MHz.

2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2016-03-09iwlwifi: add support for getting HW address from CSRSara Sharon
From 9000 family on, we need to get HW address from host CSR registers. OEM can override it by fusing the override registers - read those first, and if those are 0 - read the OTP registers instead. In addition - bail out if no valid mac address is present. Make it shared for all NICs.

802.11ac allows A-MSDU that can be up to 12KB long. Since an entire A-MSDU needs to fit into one single Receive Buffer (RB), add support for big RBs.
