Currently when none of CONFIG_NET_DSA_TAG_DSA, CONFIG_NET_DSA_TAG_EDSA and CONFIG_NET_DSA_TAG_TRAILER is defined, we get following compilation warnings:
net/dsa/slave.c:51:12: warning: 'dsa_slave_init' defined but not used [-Wunused-function] net/dsa/slave.c:60:12: warning: 'dsa_slave_open' defined but not used [-Wunused-function] net/dsa/slave.c:98:12: warning: 'dsa_slave_close' defined but not used [-Wunused-function] net/dsa/slave.c:116:13: warning: 'dsa_slave_change_rx_flags' defined but not used [-Wunused-function] net/dsa/slave.c:127:13: warning: 'dsa_slave_set_rx_mode' defined but not used [-Wunused-function] net/dsa/slave.c:136:12: warning: 'dsa_slave_set_mac_address' defined but not used [-Wunused-function] net/dsa/slave.c:164:12: warning: 'dsa_slave_ioctl' defined but not used [-Wunused-function]
Fix them by enclosing these routines under #ifdef,endif.
