My Target is not bring the Pkts to User Space which is costly. Trying to do that by using LKM. Seems to be; it is possible through skbuffers whose structure have the provision to identify the Protocol.

HI Guys,something like:
I'm a Newbie to Linux Kernel Development. Need some Clarification in
understanding Net-Filter Hooks.
Can I register only for the Necessary Packets [Ex: IPSEC etc...] from the
Net-Filters?? AFAIK ; Net-Filter Module send the Packets to the
Corresponding Module based on pre-defined HOOKS. Let us say; there are Many
Packets reaching that Hooks; and if I am Interested only in some Packets
from Net-Filter module; can I do that ???
iptables [some rules] -j ULOG
?
Check "man iptables" and see if that suits your need. FYI ULOG target
uses netlink to deliver the packet to user space for further
processing.
If this is for any application in user space, I would recommend you take a look at libPcap.
