From 5a3dba7a5fcc02b78d92c35e2ca53f21ae3402c9 Mon Sep 17 00:00:00 2001 From: Yongbae Park Date: Tue, 10 Mar 2015 11:35:07 +0900 Subject: [PATCH] net: WIZnet drivers: enable interrupts after napi_complete() The interrupt is enabled before napi_complete(). A network timeout occurs if the interrupt handler is called before napi_complete(). Fix the bug by enabling the interrupt after napi_complete(). Signed-off-by: Yongbae Park Signed-off-by: David S.
