Subject: test/eal: check invalid CPU value
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=12337cf2061e4ea544cc2cd7cd5ad4efb6ddf50a;p=dpdk.git

test/eal: check invalid CPU value

When using --lcores option, there is a limit of CPU_SETSIZE.
Currently that allows 0..1023 on Linux.

Check it is caught when this limit is exceeded.
