svn commit: r219547 - head/sys/dev/ti

[Marius Strobl]

Author: marius
Date: Fri Mar 11 22:32:17 2011
New Revision: 219547
URL: http://svn.freebsd.org/changeset/base/219547

Log:
  - Allocate the DMA memory shared between the host and the controller as
    coherent.
  - Constify the ti_devs table.
  - Don't bother to set if_mtu to ETHERMTU, ether_ifattach() does that.
  
  MFC after:	2 weeks
