Netfilter module name oddity

[Ira Abramov]

Maybe I slept through some old thread about this, but nothing came out
of searching Google about this: why do I have so many similarly named
modules in my kernel? who is the clown who decided to break some very
basic naming conventions of module filenames and give me a small heart
attack?

10809   /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_connmark.ko
12079   /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_CONNMARK.ko
10066   /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_dscp.ko
11193   /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_DSCP.ko
9885    /lib/modules/2.6.26-1-amd64/kernel/net/netfilter/xt_mark.ko

9232    /lib/modules/2.6.26-1-amd64/kernel/net/ipv4/netfilter/ipt_TTL.ko


At first glance I was sure it's some sort of a weird rootkit attempt,
but apparently it's all kosher and I'm the last silly person on the
planet to notice.

Now I just need to know why this makes sense to whoever is maintaining
this code (Rusty?) and how come I have not found any info about this
with any combination of relevant search terms...
