Subject: [PATCH net 6/7] net: hns3: fix GRO configuration error after reset
From: Yufeng Mo <moyufeng@...wei.com>
The GRO configuration is enabled by default after reset. This
is incorrect and should be restored to the user-configured value.
So this restoration is added during reset initialization.
