This isn't unique to Windows.
I assume the theory was that the program writing to the pipe should be doing
the filtering; that means you don't have to push uninteresting packets through
the pipe (pushing them through the pipe is a waste of CPU and memory bandwidth,
at minimum, and if the program writing to the pipe is receiving the packets
from over a network - e.g., a tcpdump/WinDump run on a remote machine via ssh -
it also wastes network bandwidth; in addition, it increases the risk of packet
loss).
If it's impossible to do the filtering in the program writing to the pipe, we
could have the capture loop run bpf_filter() on the incoming packets when
reading from a pipe.
