Changes all over, ath10k apparently seeing most new features this time. rtw88 also had lots of changes due to preparation for new hardware support. In this pull request there's also a new macro to include/linux/iopoll: read_poll_timeout_atomic(). This is needed by rtw88 for atomic polling. Major changes: ath11k * add debugfs file for testing ADDBA and DELBA * add 802.11 encapsulation offload on hardware support * add htt_peer_stats_reset debugfs file ath10k * enable VHT160 and VHT80+80 modes * enable radar detection in secondary segment * sdio: disable TX complete indication to improve throughput * sdio: decrease power consumption * sdio: add HTT TX bundle support to increase throughput * sdio: add rx bitrate reporting ath9k * improvements to AR9002 calibration logic carl9170 * remove buggy P2P_GO support p54usb * add support for AirVasT USB stick rtw88 * add support for antenna configuration ti wlcore * add support for AES_CMAC cipher iwlwifi * support for a few new FW API versions * new hw configs ==================== Signed-off-by: David S.

2019-12-24iwlwifi: remove lar_disable module parameterLuca Coelho1-6/+7
This is an old parameter that was used supposed to be used only when LAR was still under development. It should not be used anymore, but, since it's available, end-users have been mangling with it unnecessarily. In some cases it can cause problems because when LAR is supported the driver and the firmware do not expect it to be disabled. Signed-off-by: Luca Coelho <[email protected]>

In order to be able to select the cfg depending on the HW revision or on the RF ID, we need to set up the trans before selecting the cfg. To do so, move the elements from cfg that are needed by iwl_trans_alloc() to a separate struct at the top of the cfg, so it can be used by other cfg types as well, before selecting the rest of the configuration.

We support this, so we should advertise it. In fact, if we don't, mac80211 will do it for us (as we advertise SUPPORTS_VHT_EXT_NSS_BW to it), but that requires a memory reallocation which is wasteful: ieee80211 phy0: copying sband (band 1) due to VHT EXT NSS BW flag Set the flag here to avoid that.

2019-02-20iwlwifi: nvm-parse: use struct_size() in kzalloc()Gustavo A. R. Silva1-11/+7
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

2018-10-06iwlwifi: nvm: get num of hw addresses from firmwareNaftali Goldstein1-1/+9
With NICs that don't read the NVM directly and instead rely on getting the relevant data from the firmware, the number of reserved MAC addresses was not added to the API. This caused the driver to assume there is only one address which results in all interfaces getting the same address. Update the API to fix this. While at it, fix-up the comments with firmware api names to actually match what we have in the firmware.

Make wmm_rule be part of the reg_rule structure. This simplifies the code a lot at the cost of having bigger memory usage. However in most cases we have only few reg_rule's and when we do have many like in iwlwifi we do not save memory as it allocates a separate wmm_rule for each channel anyway.
