[dpdk-dev] [PATCH 3/3] net/ark: support for updated Tx hardware with user meta data

[Ed Czeck]

Support for version 2 of DDM hardware.
Add configurable setup for using DDM user meta data via
CONFIG_RTE_LIBRTE_ARK_DDM_USER_META
defaults to 0 for the meta data compatible with v1 hardware.
Set to 1 use uudata64.

Hi Ed,

We are trying to get rid of rte_exit() calls, reasoning is DPDK is a library and
application should decide to exit or not, and a DPDK application may be using
multiple NICs/libraries/functionalities, failure in one of them should not cause
all application to exit.

Can you please replace rte_exit() usage?

Hi Ed,

We are trying to reduce our compile time configuration, what do you think
providing same functionality with devargs?

[dpdk-dev] [PATCH v2 1/3] net/ark: add recovery code for lack of mbufs during runtime

[Ed Czeck]

Attempt to allocate smaller chunk of mbufs when larger amount is
not available.  Report error when small chunk not available.
