From 298e50ad8eb8fa12ea68bb2da45bb8ef4edcd0ec Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Mon, 27 Feb 2023 14:17:32 +0200 Subject: wifi: move raycs, wl3501 and rndis_wlan to legacy directory To clean up drivers/net/wireless move the old drivers drivers left in the directory to a new "legacy" directory. I did consider adding CONFIG_WLAN_VENDOR_LEGACY like other vendors have but then dropped the idea as these are really old drivers and hopefully we get to remove them soon. There should be no changes in compilation or in Kconfig options, merely moving files.
