Let's be a bit more generous with some of these sizes, please.

The action name might be hierarchical, i.e. include the control block and table path separated by dots, e.g. "dev5.ingress.forwarding.routing_table.set_next_hop", so:
#define ACTION_PROG_NAME_SIZE_MAX 256

Some parameters could be 128-bit IPv6 addresses, which may be specified in hex with additional characters such as '0x' or ':', so:
#define ACTION_PROG_ARG_VALUE_SIZE_MAX 64

Regards,
Cristian
