            Bug ID: 2090
           Summary: dumpcap timestamps incorrect in pcap format
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: dev@dpdk.org
          Reporter: stephen@networkplumber.org
  Target Milestone: ---

If dumpcap is outputing in legacy pcap format it gets the timestamps wrong.
The file is opened with nanosecond precision timestamps but it writes
microsecond values. This is confusion because libpcap write packet wants
nanoseconds in tv_usec field in that case.
