Fixes#2812
This patch adds support for '--lcores <map_list>'
parameter in spdk.
This parameter allow mapping of the lcores
to CPU IDs, if the system contains CPUs with IDs
greater or equal to 128 (RTE_MAX_LCORE). Such CPUs
can not be directly included in core mask
specified in '-m <mask>' parameter, as the dpdk
rejects cores if IDs are greater than 127.
The only way to use them in spdk is to map lcore
to CPU using --lcores parameters specified
in command line.
--lcores and -m parameters are mutually
exclusive. Please use only one of them.
Examples:
build/bin/nvmf_tgt --lcores 0@130
build/bin/nvmf_tgt --lcores 0@150,1@151
build/bin/nvmf_tgt --lcores "(5-7)@(10-12)"
build/bin/nvmf_tgt --lcores "(5-7)@(136,138,140)"
