From fa315cc7cb6cbb76b47c06441787b3aa85514312 Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Sun, 1 Jul 2018 14:52:06 +0300 Subject: iwlwifi: mvm: don't send keys when entering D3 [ Upstream commit 8c7fd6a365eb5b2647b2c01918730d0a485b9f85 ] In the past, we needed to program the keys when entering D3. This was since we replaced the image. However, now that there is a single image, this is no longer needed. Note that RSC is sent separately in a new command. This solves issues with newer devices that support PN offload. Since driver re-sent the keys, the PN got zeroed and the receiver dropped the next packets, until PN caught up again.
