# Review of DPDK Patch: usertools/dpdk-devbind: fix interface names on FreeBSD

## ERRORS

None identified.

## WARNINGS

None identified.

## INFO

This patch fixes a bug where interface names on FreeBSD were being cleared during additional device detail queries. The fix is straightforward and correct:

1. **Problem identification**: On FreeBSD, interface names come from `ifconfig` during initial scan, but were being overwritten by the (non-existent on BSD) sysfs-based lookup in `get_pci_device_details()`.

2. **Solution**: Preserve the interface name from the initial device data when running on BSD, since BSD doesn't populate it from sysfs.

3. **Code quality**: The fix is minimal and surgical - it only affects the BSD path and preserves existing behavior on Linux.

The `.get("Interface", "")` pattern correctly handles the case where the key might not exist, returning an empty string as a safe default.

Review-Result: CLEAN
