Subject: [PATCH net 2/3] ibmvnic: remove duplicate napi_schedule call in do_reset function
Date: Wed, 14 Apr 2021 02:46:15 -0500 [thread overview]
Message-ID: <20210414074616.11299-3-lijunp213@gmail.com> (raw)
In-Reply-To: <20210414074616.11299-1-lijunp213@gmail.com>
During adapter reset, do_reset/do_hard_reset calls ibmvnic_open(),
which will calls napi_schedule if previous state is VNIC_CLOSED
(i.e, the reset case, and "ifconfig down" case). So there is no need
for do_reset to call napi_schedule again at the end of the function
though napi_schedule will neglect the request if napi is already
scheduled.
Fixes: ed651a10875f ("ibmvnic: Updated reset handling")
