Subject: [dpdk-dev] [PATCH 1/2] config: remove explicit undefinition of unset values
Date: Tue, 25 Aug 2020 12:44:46 +0100
Message-ID: <20200825114447.135030-1-bruce.richardson@intel.com> (raw)

Rather than explicitly clearing any setting of undefined values in our
rte_config.h file, it's better to instead just add a comment that the value
is not set. Using a comment allows the user to set the value using CFLAGS
or similar mechanism without the config file clearing the value again.

The text used "<VALUE> is not set" is modelled after the kernel approach of
doing the same thing.
