Why are there these TRIGGER rules?

I removed them (using iptables-save with filtering, flushing all then iptables-restore), nothing bad happened so ffar!! The wifi also SEEMED to work more smoothly as well, but only time will tell.

Why are there these TRIGGER rules??
Code:
# iptables-save | grep -i trigger
-A PREROUTING -d 110.xxx.xxx.xxx/32 -j TRIGGER--trigger-proto --trigger-match 0-0 --trigger-relate 0-0
:trigger_out - [0:0]
-A FORWARD -i vlan2 -o br0 -j TRIGGER--trigger-proto --trigger-match 0-0 --trigger-relate 0-0
-A FORWARD -i br0 -j trigger_out
-A FORWARD -i vlan2 -o eth0 -j TRIGGER--trigger-proto --trigger-match 0-0 --trigger-relate 0-0
-A FORWARD -i eth0 -j trigger_out
-A FORWARD -i vlan2 -o eth1 -j TRIGGER--trigger-proto --trigger-match 0-0 --trigger-relate 0-0
-A FORWARD -i eth1 -j trigger_out
-A FORWARD -i vlan2 -o vlan1 -j TRIGGER--trigger-proto --trigger-match 0-0 --trigger-relate 0-0
-A FORWARD -i vlan1 -j trigger_out
-A FORWARD -i vlan2 -o wl0.1 -j TRIGGER--trigger-proto --trigger-match 0-0 --trigger-relate 0-0
-A FORWARD -i wl0.1 -j trigger_out


Update:

Removing these rules really reduced conneciton drops! Speed and signal quality was also a bit better.
