[PATCH 19.11 1/2] net/bonding: fix slave device Rx/Tx offload configuration

[Huisong Li <lihuisong@huawei.com>]

[ upstream commit b5145667785e8954077c593480ddfb2bdd708eac ]

Normally, the Rx/Tx offload capability of bonding interface is
the intersection of the capability of all slave devices. And
Rx/Tx offloads configuration of slave device comes from bonding
interface. But now there is a risk that slave device retains its
previous offload configurations which is not within the offload
configurations of bond interface.
