Bug ID: 54251
           Summary: ipconfig /all hangs / freezes / does not exit
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Used the ArchLinux package managers to install wine-git, which made sure I had
the correct build tools, git cloned, and tracked the files during install.

At least as of 2023-01-01 something's broken with networking.

My PC has two Ethernet ports on the back, and to have the option of using it as
a network switch for my laptop, they're bridged.  I also want my PC to have a
statically leased DHCP address, so the Ethernet bridge configuration might be a
little uncommon, but is not unusual and shouldn't be a problem.

It isn't a problem for ipconfig (no arguments), it isn't a problem for Linux
programs, it isn't a problem for curl under wine.

It _is_ a problem for ipconfig /all and I now suspect (after /all failed) also
a game I purchased during the recent sales.

The outputs are the same in Proton instances of wine.
