From e60ee41aaf898584205a6af5c996860d0fe6a836 Mon Sep 17 00:00:00 2001 From: Siva Reddy Kallam Date: Fri, 22 Dec 2017 16:05:29 +0530 Subject: [PATCH] tg3: Enable PHY reset in MTU change path for 5720 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. Signed-off-by: Siva Reddy Kallam Signed-off-by: Michael Chan Signed-off-by: David S.
