[PATCH -next] enic: Make dummy rfs functions inline to fix !CONFIG_RFS_ACCEL build

From: Geert Uytterhoeven
Date: Wed Jun 25 2014 - 04:31:30 EST


If CONFIG_RFS_ACCEL=n:

drivers/net/ethernet/cisco/enic/enic_main.c: In function 'enic_open':
drivers/net/ethernet/cisco/enic/enic_main.c:1603:2: error: implicit declaration of function 'enic_rfs_flw_tbl_init' [-Werror=implicit-function-declaration]
drivers/net/ethernet/cisco/enic/enic_main.c: In function 'enic_stop':
drivers/net/ethernet/cisco/enic/enic_main.c:1630:2: error: implicit declaration of function 'enic_rfs_flw_tbl_free' [-Werror=implicit-function-declaration]

Introduced in commit a145df23ef32c7b933875f334ba28791ee75766e ("enic: Add
Accelerated RFS support").

Dummy functions are provided, but their prototypes are missing, causing the
build failure. Provide dummy static inline functions instead to fix this.
