What are the rules around mbuf chain construction? (I've read man mbuf, doesnt go into much detail)
In particular, I'm assuming: - all mbufs must be same type - the head mbuf must have M_PKTHDR set - the head mbuf.m_pkthdr.len must be the len of the entire chain Anything to add? My confusion is around splitting/concatenating - When splitting an mbuf chain, the two resultant chains must be as above (heads have M_PKTHDR and mbuf.m_pkthdr.len set) right? When concatenating chains, what do you do with the M_PKTHDR that is now in the middle of the chain? m_cat doesn't seem very sophisticated in this regard. And of course update head mbuf.m_pkthdr.len Thanks Skye To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
