svn commit: r216449 - stable/7/sys/dev/cxgb

[John Baldwin]

Author: jhb
Date: Tue Dec 14 21:33:17 2010
New Revision: 216449
URL: http://svn.freebsd.org/changeset/base/216449

Log:
  When the per-queueset transmit kthread is idle, do not pass a sleep
  priority of '1' to tsleep().  This caused the priority of this kthread to
  be raised higher than every other thread in the system.  Instead, leave
  the priority of the kthread at its existing level.
  
  This is a direct commit to stable/7 as this code is no longer present in
  8.x and later.
