Hi,
I’m proposing to upload a couple of upstream patches improving Wi-Fi
connectivity in some cases especially on certain hardware.
For two of them, the relevant issues are #942164 and LP: #1867908.
Please find the attached debdiff for more details.

+Subject: Check for FT support when selecting FT suites
+
+A driver supports FT if it either supports SME or the
+NL80211_CMD_UPDATE_FT_IES command. When selecting AKM suites,
+wpa_supplicant currently doesn't take into account whether or not either
+of those conditions are met. This can cause association failures, e.g.,
+when an AP supports both WPA-EAP and FT-EAP but the driver doesn't
+support FT (wpa_supplicant will decide to do FT-EAP since it is unaware
+the driver doesn't support it). This change allows an FT suite to be
+selected only when the driver also supports FT.

+Subject: nl80211: Fix RTM NEW/DELLINK IFLA_IFNAME copy for maximum ifname
+ length
+
+If the kernel rtm_newlink or rtm_dellink send the maximum length of
+ifname (IFNAMSIZ), the event handlers in
+wpa_driver_nl80211_event_rtm_addlink() and
+wpa_driver_nl80211_event_rtm_dellink() did not copy the IFLA_IFNAME
+value. Because the RTA_PAYLOAD (IFLA_IFNAME) length already includes the
+NULL termination, that equals the IFNAMSIZ.
+
+Fix the condition when IFNAME reach maximum size.
