src/sys/dev/pci: if_wm.c
Log Message:
- Try m_defrag() to reduce the number of DMA segment if bus_dmamap_load_mbuf()
returned EFBIG. When m_defrag() is called, txqNNdefrag event counter is
incremented. If the 2nd try of bus_dmamap_load_mbuf() failed, txqNNtoomanyseg
event counter is incremented.
- Reduce the max number of DMA segemts from 256 to 64 (it's the same valuse
as other BSD's (EM_MAX_SCATTER) and more than before if_wm.c rev. 1.75's
value (40)) because we do m_defrag() now.
