Subject: [PATCH AUTOSEL for 3.18 09/24] tg3: Enable PHY reset in MTU change path for 5720
Date: Sat, 3 Feb 2018 18:05:02 +0000 [thread overview]
Message-ID: <20180203180444.10801-9-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180203180444.10801-1-alexander.levin@microsoft.com>
From: Siva Reddy Kallam <siva.kallam@broadcom.com>
[ Upstream commit e60ee41aaf898584205a6af5c996860d0fe6a836 ]
A customer noticed RX path hang when MTU is changed on the fly while
running heavy traffic with NCSI enabled for 5717 and 5719. Since 5720
belongs to same ASIC family, we observed same issue and same fix
could solve this problem for 5720.
