Change the following environment variables to kernel options:

Browse Source 
bootp -> BOOTP
    bootp.nfsroot -> BOOTP_NFSROOT
    bootp.nfsv3 -> BOOTP_NFSV3
    bootp.compat -> BOOTP_COMPAT
    bootp.wired_to -> BOOTP_WIRED_TO

- i.e. back out the previous commit.  It's already possible to
pxeboot(8) with a GENERIC kernel.

List of semicolon-separated search path for bootable kernels.
The default is
.Dq Li kernel;kernel.old .
.It Va bootp
Setting this variable tells the kernel to use BOOTP to obtain an IP address
and hostname at boot time.
The kernel must be built with
.Dv NFSCLIENT
and
.Dv NFS_ROOT
defined.
.It Va bootp.compat
Setting this variable enables a workaround for broken BOOTP daemons.
.It Va bootp.nfsroot
Setting this variable tells the kernel to NFS mount the root filesystem using
BOOTP information.
.It Va bootp.nfsv3
Setting this variable tells the kernel to use NFS version 3 to mount the root
filesystem.
.It Va bootp.wired_to
This variable may be set to the name of the interface that is to be used to
boot from when
.Va bootp
is set.
If it is not set, the system will attempt to boot from all available
interfaces, using the first one found.
.It Va console
Defines the current console.
