[Click] A new question

[Beyers Cronje]

Hi,

Please forward questions to the Click mailing list in the future, that's why
it's there for.

To answer your question. It seems that Click does not assign the ethernet
header annotation automatically, arpquerier and arpresponder does though.

So to get a pointer to your ethernet header just cast from p->data(), given
you have not used Strip before your element.

See EtherMirror source for an example.
