SVN rev 182079 on 2008-08-23 20:57:48Z by marius
- Use m_collapse(9) instead of m_defrag(9) if possible. This results
in a noticeable reduction in system time spent.
- If bus_dmamap_load_mbuf_sg(9) fails with EFBIG and we already have
defragmented the mbuf chain, don't bother to defragment and load it
a second time just yet as it's likely to fail again anyway.
