[Ethereal-dev] Help with linux socket filter

[Hans <hansni@xxxxxxxxxxxxx>]

Dear sir,
	with libpcap's pcap_compile, We can set ethernet protocol type, ip protocol type filter. Then the issue comes, can I set 802.11 type or subtype filter? Is there something else implementing the same function as pcap_compile do? I just want the filter code from a filter string, not concerning the pcap type. Of course, I can give the program the link type.
	Is there any detailed information about LSF? Where can I find BPF manual?
	Thanks a lot!

Best regards.
