[PATCH v2] net/axgbe: move offloads to Rx/Tx queue setup

[PATCH v2] net/axgbe: move offloads to Rx/Tx queue setup

[Jesna K E]

For Multiprocess dpdk applications need to retrieve the offload parameter
from the Device data directly that is shared between
primary and secondary processes rather than accessing from
Port private data (pdata) since this is not shared
between primary and secondary process .

It is not because of 'pdata' but because of ethdev in it
'rxq->pdata->eth_dev->...', eth_dev is not shared.
I will update the commit log according while merging.

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