[PATCH net-next 6/9] net: hns3: remove unnecessary ring configuration operation while resetting

From: Salil Mehta
Date: Mon Jul 16 2018 - 11:37:32 EST


From: Huazhong Tan <tanhuazhong@xxxxxxxxxx>

The configuration of the ring will be used to reinitialize the
ring after the hardware reset is completed. So we should not
release and reacquire this configuration during reset.

Fixes: bb6b94a896d4 ("net: hns3: Add reset interface implementation in client")
