Subject: [PATCH 15/18] net: dpaa2: fix mixed module-builtin object
With CONFIG_FSL_DPAA2_ETH=m and CONFIG_FSL_DPAA2_SWITCH=y (or vice
versa), dpaa2-mac.o and dpmac.o are linked to a module and also to
vmlinux even though the expected CFLAGS are different between
builtins and modules.
This is the same situation as fixed by
commit 637a642f5ca5 ("zstd: Fixing mixed module-builtin objects").
There's also no need to duplicate relatively big piece of object
code into two modules.
Introduce the new module, fsl-dpaa2-mac, to provide the common
functions to both fsl-dpaa2-eth and fsl-dpaa2-switch.
Misc: constify and shrink @dpaa2_mac_ethtool_stats while at it.
Fixes: 84cba72956fd ("dpaa2-switch: integrate the MAC endpoint support")
Suggested-by: Masahiro Yamada <masahiroy@...nel.org>
