>Description:
The BPF(4) man page:

    has some typoes;

    has some stuff not relevant to a BSD man page (as opposed to a generic man 
page for BPF added to SunOS, for example);

    still says only Ethernet, SLIP, and PPP are supported, and that no network 
types with variable-length headers (such as 802.11) are supported;

    has some stylistic glitches;

    doesn't document BIOCSRSIG or BIOCGRSIG;

    says the "k" field of a BPF instruction is signed.
