Subject: [PATCH 08/18] net: enetc: fix mixed module-builtin object
From: Masahiro Yamada <masahiroy@...nel.org>
With CONFIG_FSL_ENETC=m and CONFIG_FSL_ENETC_VF=y (or vice versa),
$(common-objs) 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").
Introduce the new module, fsl-enetc-core, to provide the common
functions to fsl-enetc and fsl-enetc-vf.
[ alobakin: add exports to common functions ]
