I'm looking for any other outdated links, that needs to be updated.

Help cannot find updated links to following resources

The link here points to an older Version, but bcc has discontinued support for compiling P4 and have removed it here . So should I remove this reference ? or Is there any other location where it can be found (I couldn't find it).

p4c/backends/ebpf/README.md

Line 8 in 8d21a8b

An older version of this compiler for compiling P4_14 is available [here](https://github.com/iovisor/bcc/tree/master/src/cc/frontends/p4).

2nd outdated link

This might not be that significant. current link

Note

I tried to correct the link to the best of my knowledge, but there might be errors in them. Kindly re-review the links once.

For the outdated link to bcc, it might be nice to explicitly mark it as a "historical reference only". I only suggest that in case someone comes across it in the future and decides to investigate further to make changes that cause it to be supported again, or decides to create a system with older versions of software where they can try it out.

Sure ! So should leave a link to the point of 'bcc' repository before the support for P4 was removed
or remove the link?

I would add an annotation saying that this link is for historical reference only.

You can ignore it. We should deprecated cpplint at some point.
