[PATCH 2/2 net-next] mlxsw: spectrum_router: Constify struct devlink_dpipe_table_ops

From: Christophe JAILLET
Date: Sun Jun 02 2024 - 10:19:35 EST


'struct devlink_dpipe_table_ops' are not modified in this driver.

Constifying these structures moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig:
Before:
======
text data bss dec hex filename
15557 712 0 16269 3f8d drivers/net/ethernet/mellanox/mlxsw/spectrum_dpipe.o

After:
=====
text data bss dec hex filename
15789 488 0 16277 3f95 drivers/net/ethernet/mellanox/mlxsw/spectrum_dpipe.o
