Subject: devtools: restore null test
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=85fc9b2542aa13bb0e3838458795c8aaccb77541;p=dpdk.git

devtools: restore null test

This small testpmd test was not working for a long time
because of several changes in EAL and mempool.
The 3 main issues solved are:
	- Make --no-huge working by specifying an amount of memory
		to allocate in legacy mode, and disabling mlockall.
	- Load a mempool handler in shared library case.
	- Support meson
