From: Johannes Berg Date: Fri, 24 Feb 2023 12:59:34 +0000 (+0100) Subject: wifi: wext: warn about usage only once X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=52fd90638a7269be2a6f6cf1e4dea6724f8e13b6;p=linux.git wifi: wext: warn about usage only once Warn only once since the ratelimit parameters are still allowing too many messages to happen. This will no longer tell you all the different processes, but still gives a heads-up of sorts. Also modify the message to note that wext stops working for future Wi-Fi 7 hardware, this is already implemented in commit 4ca69027691a ("wifi: wireless: deny wireless extensions on MLO-capable devices") and is maybe of more relevance to users than the fact that we'd like to have wireless extensions deprecated. The issue with Wi-Fi 7 is that you can now have multiple connections to the same AP, so a whole bunch of things now become per link rather than per netdev, which can't really be handled in wireless extensions.
