New Revision: 262967
URL: http://svnweb.freebsd.org/changeset/base/262967

Log:
  MFC r261535:
  Add support for MegaRAID Fury cards. The main change needed to boot from a
  9341-4i controller was to ensure that scatter/gather lists are ended with
  an end-of-list marker. Both the mrsas and Linux megaraid_sas drivers use
  this marker with Invader cards as well, so we do the same thing, though
  it is apparently not strictly necessary.
