Author: bz Date: Tue Jan 7 16:58:39 2020 New Revision: 356455 URL: https://svnweb.freebsd.org/changeset/base/356455 Log: MFC r355070: Allow kernel to compile without BPF. r297816 added some bpf magic for VIMAGE unconditionally which no longer allows kernels to compile without bpf (but with other networking). Add the missing ifdef checks and allow a kernel to compile without bpf again.
