svn commit: r283069 - head/sys/boot/arm/uboot

New Revision: 283069
URL: https://svnweb.freebsd.org/changeset/base/283069

Log:
  Enable the NETIF_OPEN_CLOSE_ONCE option for ubldr.  This keeps the network
  interface open continuously instead of closing it after each filesystem
  access and reopening it before the next (causing it to re-obtain network
  params each time).  This vastly speeds up netbooting.
