libgtp uses statically-sized arrays for storing various things, including pdp contexts. This means that no more than 1024 PDP contexts are possible in osmo-sgsn or osmo-ggsn at the moment. This seems very low even for small / private networks.

A quick change might be to increase the #define, but we'd have to see what kind of implications this has on memory consumption as well as runtime complexity.

In the end, dynamic allocations is what we do in all other (native) osmocom projects, so I don't see why we should keep (inherited) libgtp using fixed static allocations imposing arbitrary limits.
