[PATCH v4 04/25] net: fman: Store en/disable in mac_device instead of mac_priv_s

From: Sean Anderson
Date: Mon Jul 25 2022 - 11:11:38 EST


All macs use the same start/stop functions. The actual mac-specific code
lives in enable/disable. Move these functions to an appropriate struct,
and inline the phy enable/disable calls to the caller of start/stop.
