From 7489bdadb7d17d3c81e39b85688500f700beb790 Mon Sep 17 00:00:00 2001 From: hayeswang Date: Thu, 26 Jan 2017 09:38:34 +0800 Subject: [PATCH] r8152: check rx after napi is enabled Schedule the napi after napi_enable() for rx, if it is necessary. If the rx is completed when napi is disabled, the sheduling of napi would be lost. Then, no one handles the rx packet until next napi is scheduled. Signed-off-by: Hayes Wang Signed-off-by: David S.
