svn commit: r301119 - head/sys/dev/cxgbe/cxgbei

Log:
  Reduce the priority of cxgbei(4) driver, so it doesn't get chosen
  by default.  This is a workaround for a too simplistic ICL module
  choosing mechanism.  To use it, specify offload in ctl.conf
  or iscsi.conf.
  
  This fixes a problem where "kldload cxgbei" wedges the iSCSI stack,
  if you don't have a Chelsio card installed, or the endpoints of the
  iSCSI session are not reachable through addresses configured
  on that interface.
