[dpdk-dev] [PATCH] tools: fix json output of pmdinfo

[Olivier Matz]

Using dpdk-pmdinfo with the '-r' flag does not produce a json output as
documented. Instead, the python representation of the json object is
shown, which is nearly the same, but cannot be properly parsed by a json
parser.

python repr (before):
  {u'pci_ids': [[5549, 1968, 65535, 65535]], u'name': u'vmxnet3'}
json (after):
  {"pci_ids": [[5549, 1968, 65535, 65535]], "name": "vmxnet3"}

Fixes: c67c9a5c646a ("tools: query binaries for HW and other support information")
