RE: [PATCH] examples/l3fwd: fix conf propagation to RX queues

[Konstantin Ananyev <konstantin.ananyev@huawei.com>]

> When configuring RX queues, the default port configuration was used,
> even though it was modified before. This results in the
> 'relax-rx-offload' not being respected for RX queues.
> This commit uses 'rte_eth_dev_conf_get()' to obtain the device
> configuration structure instead.
