The Wireshark display filter code, for the filter "ip.dst ==
207.35.208.194 or ip.src == 207.35.208.194", looks for IP addresses
wherever they appear in the packet.

The libpcap/WinPcap capture filter code, for the filter "host
207.35.208.194", generates BPF code that looks for IP addresses under
the assumption that there are no VLAN headers.  The packets not being
seen have VLAN headers.

The filter

        host 207.35.208.194 or (vlan and host 207.35.208.194)

(you will need to quote that if you put it on the command line) sees all
the packets in the file; it will check for IP addresses with no VLAN
headers or with one level of VLAN header.
