[dpdk-dev] [PATCH] config: remove useless lines for DPAA2

[dpdk-dev] [PATCH] config: remove useless lines for DPAA2

[Thomas Monjalon]

Some comments are not relevant in a config which only overrides
the default config.

The option CONFIG_RTE_LIBRTE_DPAA2_DEBUG_DRIVER is already disabled
by default so it can be removed from this file.

I think DEBUG_DRIVER should exist in local config so that a developer 
can easily toggle it without modifying the common_base, which should 
serves as repository rather than toggle.

I do see the problem that having an option in common_base and then 
having it again in local config without overriding (=n) - is non-intuitive.

But, I still feel it is easier to control changes in local config - 
(make T=<local config>) is easily visible.

No, the file to be modified is .config in the build directory,
not the default config.

It is not a local config file.
The local config is .config.

In my environment I prefer changing the platform config rather than 
local .config as that way I can track changes through git.

Sorry, allow me to rephrase my previous wordings:

s/local config/platform config/

Anyways, this is just my personal preference - not a big inconvenience.
Thanks for the patch.
