svn commit: r253889 - head/sys/dev/cxgbe

[Navdeep Parhar]

Author: np
Date: Fri Aug  2 17:44:19 2013
New Revision: 253889
URL: http://svnweb.freebsd.org/changeset/base/253889

Log:
  Fix previous commit (r253873).  "cong" has one bit per channel but the
  congestion channel map has 1 nibble per channel.  So bits wxyz need to
  be blown up into 000w000x000y000z.
