>Description:
        A kernel using bpf (almost all?) does not build with revision 1.99
        of src/sys/net/bpf.c.  Looking at the code, one can see that 'ioflag'
        is undefined in a new function, bpf_waitfordata.  Furthermore, in
        line 1748, the code seems to be garbled (a function ends but the
        code continues).

        Here is a log of the failure:

        Build a kernel with bpfilter enabled.

        Unknown.
