From 97affcfa15bbcd943393a02f085f10193c8e75ac Mon Sep 17 00:00:00 2001 From: Merlijn Wajer Date: Sun, 12 Dec 2021 23:13:08 +0100 Subject: [PATCH] wl1251: specify max. IE length This fix is similar to commit 77c91295ea53 ("wil6210: specify max. IE length"). Without the max IE length set, wpa_supplicant cannot operate using the nl80211 interface. This patch is a workaround - the number 512 is taken from the wlcore driver, but note that per Paul Fertser: there's no correct number because the driver will ignore the data passed in extra IEs.
