UCI, network:

        option gateway '10.20.30.41'

results to:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
172.0.0.0       10.20.30.41     255.240.0.0     UG    0      0        0 eth3

Steps to reproduce

Add a route to 172.16.0.0/12 via UCI or LUCI

Actual behaviour

actually, the result is a route to 172.0.0.0/12 instead of 172.16.0.0/12

Expected behaviour

No response

Additional info

I'm sure, this bug comes with one of the latest updates because I had already installed 23.05 with functional routing

netifd: fix IPv4 route target masking
842932a 
A previous commit supposed to mask out excess host bits in route targets
failed to correctly calculate the mask value, causing it to produce
improper results for certain mask lengths.
