Subject: [PATCH] net: ethernet: broadcom: have drivers select DIMLIB as needed

From: Randy Dunlap <rdunlap@...radead.org>

NET_VENDOR_BROADCOM is intended to control a kconfig menu only.
It should not have anything to do with code generation.
As such, it should not select DIMLIB for all drivers under
NET_VENDOR_BROADCOM.  Instead each driver that needs DIMLIB should
select it (being the symbols SYSTEMPORT, BNXT, and BCMGENET).

Fixes: 4f75da3666c0 ("linux/dim: Move implementation to .c files")
