which network environment is available for testing. Without this, the parts
that rely on network will be automatically skipped.

# USB enumeration needs to be performed prior to network tests.
# This variable may be omitted if its value is False.

# Boolean indicating whether the Ethernet device is attached to PCI, and hence
# PCI enumeration needs to be performed prior to network tests.
# This variable may be omitted if its value is False.

# True if a DHCP server is attached to the network, and should be tested.
# If DHCP testing is not possible or desired, this variable may be omitted or
# set to False.
