Hi, What is the difference between if (m->m_flags & M_VLANTAG) and if (ether_type == ETHERTYPE_VLAN) ? I suppose that m->m_flags are set using ether_type at one point. Still, I was not able to find a location in the source where it would happen. The fact is, I do not understand the difference between these two things, nor do I understand why we need the code in if_ethersubr.c[691-717] Thanks a lot ! -- Gregory
