BUG FIXES:

Packet Filter:
- Stateful mechanism was dropping packets with "Invalid Ack" when using IPSEC. This was caused by an incorect IP datagram length in the IP header received from TCP for incoming packets.
- Filter GUID for "Log only" filters was not always properly set.
- Corrected timeouts calculation. (based on the time elapsed from reboot as opposed to system time).

NAT:
- Corrected NAT behavior when checksum offloading is enabled (ex. on 3Com cards.)
- Added ICMP Type pairs 35-36, 37-38 to ICMP NATEntry table.
- Fixed incorrect Import NAT rules."
