Ipchains log question

[SCHWACK <schwack@opticnerve.dhs.org>]

I have a question about ipchains logs that i've never been able to find a
definitive answer on.

With the following log entry (wrapped for readability):

Jun 21 07:22:01 AMNESIA kernel: Packet log: input ACCEPT eth0 PROTO=6
192.168.0.1:2915 192.168.0.3:44 L=48 S=0x00 I=8979 F=0
x4000 T=128 SYN (#1)

What do the fields after the destination address and port
(192.168.0.3:44) refer to? I can speculate that L may be for length and
SYN obviously for the SYN packet type, but what's this other stuff talking
about?

Thanks in advance
