If the user requests to use an lcore above 128 using -l,
the eal will exit with "EAL: invalid core list syntax" and
very little else useful information.
This patch adds some extra information suggesting to use --lcores
so that physical cores above RTE_MAX_LCORE (default 128) can be
used. This is achieved by using the --lcores option by mapping
the logical cores in the application to physical cores.
For example, if "-l 12-16,130,132" is used, we see the following
additional output on the command line:
EAL: lcore 132 >= RTE_MAX_LCORE (128)
EAL: lcore 133 >= RTE_MAX_LCORE (128)
EAL: To use high physical core ids, please use --lcores to map them
to lcore ids below RTE_MAX_LCORE,
EAL: e.g. --lcores 0@12,1@13,2@14,3@15,4@16,5@132,6@133
The same is added to -c option parsing.
For example, if "-c 0x300000000000000000000000000000000" is
used, we see the following additional output on the command line:
EAL: lcore 128 >= RTE_MAX_LCORE (128)
EAL: lcore 129 >= RTE_MAX_LCORE (128)
EAL: To use high physical core ids, please use --lcores to map them
to lcore ids below RTE_MAX_LCORE,
EAL: e.g. --lcores 0@128,1@129
