>Environment:
NetBSD 5.0 sparc
Architecture: sparc
Machine: sparc
>Description:
	net-boot using BOOTPARAM fails on NetBSD 5.0 sparc.

>How-To-Repeat:
	netboot NetBSD 5.0 with BOOTPARAM

>Fix:
	Even if some parameters are missing after three methods
	(static, DHCP, BOOTPARAMS), not reach to NFS_BOOT_ALLINFO,
	net-boot should not stopped.
	This caused by adding sys/nfs/nfs_bootparams.c *flags check.

   268          if ((*flags & NFS_BOOT_ALLINFO) != NFS_BOOT_ALLINFO)
   269                  return error ? error : EADDRNOTAVAIL;
