From: Martin Habets <habetsm.xilinx@...il.com>

Subject: [PATCH net-next 06/28] sfc/siena: Rename functions in efx.h to
avoid conflicts with sfc
From: Martin Habets <martinh@...inx.com>
For siena use efx_siena_ as the function prefix.
efx_mtd_remove_partition can become static as it is no longer called
from other files.
efx_ticks_to_usecs and efx_xmit_done_single are not used in Siena, so
they are removed.
