Subject: [PATCH V2] e1000: Add netif_napi_del in the normal path and error path to match netif_napi_add
Date: Sun, 21 Dec 2014 08:52:54 +0800	[thread overview]
Message-ID: <549619E6.8070503@163.com> (raw)
In-Reply-To: <20141220.143005.1130435723139487537.davem@davemloft.net>

Th driver lacks netif_napi_del in the normal path and error path to match the call of netif_napi_add in e1000_probe.

This patch fixes this problem, and it has been tested in runtime.
