[V2] net/bonding: fix bond3 and bond4 process mbuf fast free
Checks
Commit Message
The RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE offload can't be used in bonding
mode Broadcast and mode 8023AD. Currently, bonding driver forcibly removes
from the dev->data->dev_conf.txmode.offloads and processes as success in
bond_ethdev_configure(). But this still cause that rte_eth_dev_configure()
fails to execute because of the failure of validating Tx offload in the
eth_dev_validate_offloads(). So this patch moves the modification of txmode
offlaods to the stage of adding slave device to report the correct txmode
offloads.

-v2: report the correct txmode offloads based on bonding mode in the
bonding driver, and not in testpmd.

Applied to dpdk-next-net/main, thanks.
