If CONFIG_NET_HWBM is not set, then these stub functions in <net/hwbm.h> should be declared static to avoid trying to export them from any driver that includes this. Note, add __maybe_unused as the marvell mvneta.c driver will otherwise cause gcc warnings from these. Fixes the following sparse warnings: ./include/net/hwbm.h:24:6: warning: symbol 'hwbm_buf_free' was not declared. Should it be static? ./include/net/hwbm.h:25:5: warning: symbol 'hwbm_pool_refill' was not declared. Should it be static? ./include/net/hwbm.h:26:5: warning: symbol 'hwbm_pool_add' was not declared.
