if vrx518_tc is the only instance using those new fields, wouldn't it be 
nicer and neater if you remove the usage of the added ATM_* fields from 
dcdp/atm_tc.c and then just drop 998-lantiq-atm-hacks.patch completely?

That'll get rid of patching the atm uapi header altogether, which isn't 
nice to begin with and it's one less spot to maintain.
