### Patch Overview
This patch fixes a bug on FreeBSD where network interface names were being cleared when retrieving additional device details. The fix preserves the interface name obtained from `ifconfig` during the initial scan by explicitly copying it before updating with details from `get_pci_device_details()`.

### Code Analysis

**The fix is correct.** On FreeBSD:
1. Initial scan populates `devices[d]["Interface"]` from `ifconfig` output
2. Later, `get_pci_device_details()` returns details without an `Interface` field (since BSD lacks Linux sysfs paths)
3. The `.update()` call would leave `Interface` as an empty string from the `get_pci_device_details()` return
4. The patch preserves the original interface name by explicitly copying it before the update

**Code quality:**
- The `.get("Interface", "")` fallback handles the case where the initial scan didn't populate an interface name
- The conditional is appropriately scoped to BSD only
- The fix is minimal and doesn't affect Linux behavior

**Style compliance:**
- Python code formatting appears consistent with the file
- Comment is clear and explains the BSD-specific behavior
- 4-space indentation is used correctly

**Process compliance:**
- Fixes tag references the commit that introduced the issue
- Cc: stable is appropriate for a bug fix
- The change is limited to usertools (Python script), so no C style rules apply
