Cilium: Documentation: mention eBPF

[aalemayhu]

The current documentation presents BPF as a new thing without any mention of eBPF.
I don't hear people distinguishing much between classic BPF and eBPF, but IMO there is educational value for the documentation to at least mention eBPF.

Agreed. We should have an extensive section about BPF and also explain difference and origin.

Makes sense, I think it could be a chapter by itself discussing this (incl. tc and xdp hook).

Here's the built version from the PR, see BPF and XDP Guide chapter for an initial start:

Sweet, will print out and read soon. This issue can be closed when it's merged or you could also just add a Fixes: #528 in the commit message that should close this when it hits master.

Thanks.
