Subject: [PATCH net-next 2/9] 8139cp: use napi_complete_done()
Date: Sat, 4 Feb 2017 10:20:31 -0800 [thread overview]
Message-ID: <20170204182038.3752-3-edumazet@google.com> (raw)
In-Reply-To: <20170204182038.3752-1-edumazet@google.com>
Use napi_complete_done() instead of __napi_complete() to :
1) Get support of gro_flush_timeout if opt-in
2) Not rearm interrupts for busy-polling users.
3) use standard NAPI API.
4) Eventually get rid of napi_gro_flush() in the future.
