sa.c becomes too big, so decided to split it into 3 chunks: - sa.c - control path related functions (init/fini, etc.) - esp_inb.c - ESP inbound packet processing - esp_outb.c - ESP outbound packet processing Plus few changes in internal function names to follow the same code convention. No functional changes introduced. Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Acked-by: Akhil Goyal <akhil.goyal@nxp.com>
