[dpdk-dev] [PATCH] net/bonding: fix offloading configuration

["Min Hu (Connor)" <humin29@huawei.com>]

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, part offloadings of the bonding device will not take effect
by using dev_configure(). Because the related configuration will not be
delivered to the slave devices in this way.

The offloading capability of the bonding device is the intersection of
the capability of all slave devices. Based on this, the following functions
are added to the bonding driver:
1. If a Tx offloading is within the capability of the bonding device (i.e,
all the slave devices support this Tx offloading), the enabling status of
the offloading of all slave devices depends on the configuration of the
bonding device.

2. For the Tx offloading that is not within the Tx offloading capability
of the bonding device, the enabling status of the offloading on the slave
devices is irrelevant to the bonding device configuration. And it depends
on the original configuration of the slave devices.

Fixes: e8b3e1a9b1bb ("net/bonding: switch to new offloading API")
