[dpdk-dev] [PATCH v2 2/2] eal: fix parsing of eal option --lcores

[Wei Dai <wei.dai@intel.com>]

The '-' in lcore set overrides cpu set of following
lcore set in the argument of EAL option --lcores.
for example --locres '0-2,(3-5)@(3,4),6@(5,6),7@(5-7)',
0-2 make lflags=1 which indeed suppress following
cpu set (3,4), (5,6) and (5-7) after @ .

Fixes: 53e54bf81700 ("eal: new option --lcores for cpu assignment")
