Attach XDP program to interface before running ctstraffic

[Alan-Jowett]

This pull request includes several changes to the .github/workflows/ebpf.yml file that improve the testing process for eBPF (Extended Berkeley Packet Filter) on Windows. The most significant changes include adding a step to clean up the installer, updating the anti-malware signatures for Windows Defender, updating the URL for downloading the bpf_performance repository artifacts, and adding steps to run the CTS traffic with and without XDP installed to measure performance impacts. There are also changes to merge and upload the results.

Installer cleanup:

• Added a step to clean up the installer by executing a PowerShell script from a URL. This helps to ensure a clean environment for each test run.

Windows Defender updates:

• Updated the anti-malware signatures for Windows Defender to prevent false positives that could interfere with the tests.

Repository artifacts:

• Updated the URL for downloading the bpf_performance repository artifacts. This ensures that the latest version of the artifacts is used for testing.

CTS traffic testing:

• Added steps to run the CTS traffic with and without XDP installed to measure the impact of XDP on performance. This provides more comprehensive performance data.

Results merging and uploading:

• Added steps to merge and upload the results of the CTS traffic tests and the BPF performance tests. This makes it easier to compare the results and analyze the performance data.

Windows Defender exclusions restoration:

• Added a step to restore Windows Defender exclusions after the tests are completed. This ensures that the system is returned to its original state after testing.

@nibanks @mtfriesen How do I determine why XDP is refusing the attach? What logs can I gather?

Got traces.

Issue remains:
IfIndex passed to netsh doesn't match ifindex in trace.

Something doesn't match here.

[Alan-Jowett]

Resolved. @mtfriesen pointed out there was a typo.

[Alan-Jowett]

BPF program is returning 0 instead of XDP_PASS, which causes XDP to drop the packets.
