From 5b240d13861e85a18a9b363b23a00ea934631098 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jonas=20Dre=C3=9Fler?= Date: Sat, 16 Oct 2021 17:32:43 +0200 Subject: [PATCH] mwifiex: Send DELBA requests according to spec MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit While looking at on-air packets using Wireshark, I noticed we're never setting the initiator bit when sending DELBA requests to the AP: While we set the bit on our del_ba_param_set bitmask, we forget to actually copy that bitmask over to the command struct, which means we never actually set the initiator bit. Fix that and copy the bitmask over to the host_cmd_ds_11n_delba command struct.
