Parameters

• mbuf:

  The mbuf.

  The minimum length of space that should follow the new data location.

Discussion

mbuf_align_32 is a replacement for M_ALIGN and MH_ALIGN. mbuf_align_32 will set the data pointer to a location aligned on a four byte boundry with at least 'len' bytes between the data pointer and the end of the data block.
