Bug ID: 13748
Summary: Wireshark needs a way to specify arbitrary strings as
capture devices
Product: Wireshark
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: Enhancement
Priority: Medium
Component: Qt UI
Assignee: bugzilla-ad...@wireshark.org
Reporter: g...@alum.mit.edu
Target Milestone: ---
Build Information:
N/A

I just checked into the libpcap repository source Luigi Rizzo's code for
capturing on netmap devices:
https://www.freebsd.org/cgi/man.cgi?query=netmap&sektion=4
The device "names" that can be specified aren't identifiers for devices, they
include expressions that specify how to plumb the device. See the syntaxes
described in the section for the NIOCREGIF ioctl.
So the netmap support doesn't attempt to enumerate devices, and there won't be
any netmap devices in the local capture device list.
To capture on netmap devices, there will need to be a way to let the user type
in the appropriate string and have Wireshark capture on that device.
Perhaps adding [+] and [-] buttons to the "Capture Interfaces" dialog, letting
you add devices (specifying a name) and remove devices (enabled only if you've
selected an added device).
