New Revision: 247264
URL: http://svnweb.freebsd.org/changeset/base/247264

Log:
  Turn off fast posting for the ISP2100- I'd forgotten that it actually
  might have been enabled for them- now that we use all 32 bits of handle.
  Fast Posting doesn't pass the full 32 bits.
  
  Noticed by: Bugs in NetBSD. Only a NetBSD user might actually still use such old hardware.
  MFC after:	1 week
