Type

• Bug fix
• Feature addition
• Feature update
• Documentation
• Build Infrastructure

Side Effects

• Breaking change
• Non-functional change

Goals

• Relax interface restrictions in implementation, specifically related to the AccessPoint* hierarchy.

Technical Details

• Change AccessPointDiscoveryAgentOperationsNetlink from accepting the generic IAccessPointFactory to a AccessPointFactoryLinux, which is intended to be the base for all Linux implementations. Use this to allow capturing the ready-made Nl80211Interface which is then passed to the AccessPointLinux instance.
• Add Linux-specific wifi test helper library.

Test Results

• All unit tests pass.
• netremote-cli wifi enumaps works as expected.

Reviewer Focus

• None

Future Work

• Make use of the Nl80211Interface to populate access point capabilities in the API.

Checklist

• Build target all compiles cleanly.
• clang-format and clang-tidy deltas produced no new output.
• Newly added functions include doxygen-style comment block.
