[dpdk-dev] [PATCH] app/testpmd: fix offloads for the newly attached port

[Viacheslav Ovsiienko]

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.

Two above lines should be swapped.

The patch duplicates too much from init_config() function.
Please, factor out a helper function to do the job and
use it in init_config() and reconfig().

[dpdk-dev] [PATCH v2] app/testpmd: fix offloads for the newly attached port

[Viacheslav Ovsiienko]

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.
