Annotated Snippet
#!/bin/bash
# SPDX-License-Identifier: GPL-2.0
# This test uses standard topology for testing gretap. See
# mirror_gre_topo_lib.sh for more details.
#
# Test for "tc action mirred egress mirror" when the underlay route points at a
# bridge device without vlan filtering (802.1d). The device attached to that
# bridge is a VLAN.

Annotation
- Atlas domain: Support Tooling And Documentation / tools.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
