Subject: [PATCH 4.19 25/86] bnxt_en: Fix race when modifying pause settings.
Date: Mon, 27 Jul 2020 16:03:59 +0200	[thread overview]
Message-ID: <20200727134915.625690928@linuxfoundation.org> (raw)
In-Reply-To: <20200727134914.312934924@linuxfoundation.org>

From: Vasundhara Volam <vasundhara-v.volam@broadcom.com>

[ Upstream commit 163e9ef63641a02de4c95cd921577265c52e1ce2 ]

The driver was modified to not rely on rtnl lock to protect link
settings about 2 years ago.  The pause setting was missed when
making that change.  Fix it by acquiring link_lock mutex before
calling bnxt_hwrm_set_pause().

Fixes: e2dc9b6e38fa ("bnxt_en: Don't use rtnl lock to protect link change logic in workqueue.")
