2019-11-14qtnfmac: send EAPOL frames via control pathSergey Matyukevich5-20/+14
Send EAPOL frames via control path so they can be treated in a different way rather than normal data frames. In this case EAPOLs are sent with higher priority and with disabled aggregation and encryption. Besides, all devices benefit from sending EAPOL frames via high priority path, so move the functionality from chip specific to common code.

2019-06-25qtnfmac: Use struct_size() in kzalloc()Gustavo A. R. Silva1-3/+2
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 ieee80211_regdomain { ... struct ieee80211_reg_rule reg_rules[]; }; instance = kzalloc(sizeof(*mac->rd) + sizeof(struct ieee80211_reg_rule) * 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, reg_rules, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

This patch modifies location of debugfs entries and their naming conventions to support multiple wireless cards on pcie host.

2019-02-08qtnfmac: enable WPA3 SAE supportSergey Matyukevich5-2/+145
In the case of SAE AP, drivers offload authentication to user-space software, e.g. hostapd. For FullMAC drivers the procedure is as follows. If auth_type is SAE and user space indicates external authentication capability, then driver requests authentication offload to user-space software using cfg80211_external_auth_request call. From that point, auth frame exchange is performed transparently for driver: user-space software sends/receives mgmt frames using mgmt_tx/mgmt_frame_register cfg80211 callbacks. As soon as authenitcation is completed, user-space software notifies driver about its status using external_auth cfg80211 callback.
