net/ncsi: fix ncsi_vlan_rx_{add,kill}_vid references
We get a new link error in allmodconfig kernels after ftgmac100 started using the ncsi helpers: ERROR: "ncsi_vlan_rx_kill_vid" [drivers/net/ethernet/faraday/ftgmac100.ko] undefined! ERROR: "ncsi_vlan_rx_add_vid" [drivers/net/ethernet/faraday/ftgmac100.ko] undefined! Related to that, we get another error when CONFIG_NET_NCSI is disabled: drivers/net/ethernet/faraday/ftgmac100.c:1626:25: error: 'ncsi_vlan_rx_add_vid' undeclared here (not in a function); did you mean 'ncsi_start_dev'? drivers/net/ethernet/faraday/ftgmac100.c:1627:26: error: 'ncsi_vlan_rx_kill_vid' undeclared here (not in a function); did you mean 'ncsi_vlan_rx_add_vid'? This fixes both problems at once, using a 'static inline' stub helper for the disabled case, and exporting the functions when they are present. Fixes: 51564585d8c6 ("ftgmac100: Support NCSI VLAN filtering when available") Fixes: 21acf63013ed ("net/ncsi: Configure VLAN tag filter") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.
