It supports one new eal long option '--lcores' for EAL thread cpuset assignment.
The format pattern:
--lcores='<lcores[@cpus]>[<,lcores[@cpus]>...]'
lcores, cpus could be a single digit/range or a group.
'(' and ')' are necessary if it's a group.
If not supply '@cpus', the value of cpus uses the same as lcores.
e.g. '1,2@(5-7),(3-5)@(0,2),(0,6),7-8' means starting 9 EAL thread as below
lcore 0 runs on cpuset 0x41 (cpu 0,6)
lcore 1 runs on cpuset 0x2 (cpu 1)
lcore 2 runs on cpuset 0xe0 (cpu 5,6,7)
lcore 3,4,5 runs on cpuset 0x5 (cpu 0,2)
lcore 6 runs on cpuset 0x41 (cpu 0,6)
lcore 7 runs on cpuset 0x80 (cpu 7)
lcore 8 runs on cpuset 0x100 (cpu 8)
