30 This header defines an API for interacting with mbufs. mbufs are the
33 mbufs are used to store various items in the networking stack. The
37 than would fit in an mbuf, external data is used. Most mbufs with
40 mbufs can be chained, contiguous data in a packet can be found by
87 @abstract Types of mbufs.
88 @discussion Some mbufs represent packets, some represnt data waiting
89 on sockets. Other mbufs store control data or other various

218 @field mbufs Number of mbufs (free or otherwise).
230 Anything smaller than this should be placed in chained mbufs.

749 If mbuf_copydata is unable to allocate enough mbufs to grow the
757 bytes, mbufs will be allocated to create the space.
