> Subject: [dpdk-stable] [PATCH v3] app/testpmd: fix offloads for the newly
> attached port
> 
> For the newly attached ports (with "port attach" command) the default offloads
> settings, configured from application command line, were not applied, causing
> port start failure following the attach.
> 
> For example, if scattering offload was configured in command line and rxpkts
> was configured for multiple segments, the newly attached port start was failed
> due to missing scattering offload enable in the new port settings. The missing
> code to apply the offloads to the new device and its queues is added.
> 
> The new local routine init_config_port_offloads() is introduced, embracing the
> shared part of port offloads initialization code.
