Subject: [PATCH 01/11] wil6210: do not reset FW in STA to P2P client interface switch
Date: Sun, 16 Jun 2019 10:25:57 +0300
Message-ID: <1560669967-23706-2-git-send-email-merez@codeaurora.org> (raw)
In-Reply-To: <1560669967-23706-1-git-send-email-merez@codeaurora.org>

From: Alexei Avshalom Lazar <ailizaro@codeaurora.org>

Currently the FW is reset on every interface type change, because
of various FW bugs.
FW reset is not required when switching from STA to P2P client, hence
can be skipped.
