Subject: [PATCH net v2] net: ethernet: ti: Fix mixed module-builtin object
With CONFIG_TI_K3_AM65_CPSW_NUSS=y and CONFIG_TI_ICSSG_PRUETH=m,
k3-cppi-desc-pool.o is linked to a module and also to vmlinux even though
the expected CFLAGS are different between builtins and modules.
The build system is complaining about the following:
k3-cppi-desc-pool.o is added to multiple modules: icssg-prueth
ti-am65-cpsw-nuss
Introduce the new module, k3-cppi-desc-pool, to provide the common
functions to ti-am65-cpsw-nuss and icssg-prueth.
Fixes: 128d5874c082 ("net: ti: icssg-prueth: Add ICSSG ethernet driver")
