Log:
MFC if_stge.c rev 1.12 to RELENG_7.
Use m_collapse(9) to collapse mbuf chains instead of relying on
shortest possible chain of mbufs of m_defrag(9). What we want is
chains of mbufs that can be safely stored to a Tx descriptor which
can have up to STGE_MAXTXSEGS mbufs. The ethernet controller does
not need to align Tx buffers on 32bit boundary. So the use of
m_defrag(9) was waste of time.
