Fail to run hello_xdp

[ZENOTME]

Hi, I failed to run hello_xdp in the master branch. I'm not sure whether there is a problem with my env set or I forgot to install something.

system version:

error msg:

I guess it's caused by the version. I switch to feat/use-libxdp-sys and it works.🥵

I believe this was an issue with the previous code using b'hello' instead of a correctly structured ethernet packet. it's fixed in the branch you mention

closing this since feat/use-libxdp-sys is now merged
