+Subject: [PATCH] brcmfmac: increase timeout for tx eapol
+
+When keys get set and updated this has to happen after eapol got
+transmitted (without key or old key) before the key can be updated.
+To make sure the order of sending eapol and configuring key is done
+correctly a timeout for tx of eapol is applied. This timeout is set
+to 50 msec, which is not always enough. Especially in AP mode and
+key updates the timeout may need to be much longer because client(s)
+can be in powersave. Increase the timeout from 50 to 950 msec.
