net: lan966x: Expose functions that are needed by FDMA
Expose the following functions 'lan966x_hw_offload', 'lan966x_ifh_get_src_port' and 'lan966x_ifh_get_timestamp' in lan966x_main.h so they can be accessed by FDMA. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
