The message buffer struct(mbuf): Linux equivalent

Is there an equivalent in Linux for the mbuf(message buffer)data structures that holds the actual packet data that is to be transmitted over networks? I assumed that this is a generic UNIX structure but apparently it's unique to FreeBSD.

So it turns out that the mbuf(message buffer) and pbuf(packet buffer) structures are part of the FreeBSD network stack. The sk_buff(socket buffer) is the Linux equivalent of mbuf and contains all the information about the message data being transmitted as well as the packet structure.

There's the sk_buff, I don't know enough to say how much alike it is with mbuf in practise: Networking: sk_buff.
