By moving the fpe_cfg field to the stmmac_priv data, stmmac_fpe_cfg
becomes platform-data eventually, instead of a run-time config.

Not sure whether it's supposed to be alphabetically ordered, but using
additional spaces to align the names seems an abnormal approach. I
failed to find any similar sample in kernel. So seeing the driver
doesn't implement the forward declarations as you suggest I'd convert
this to just:

 struct stmmac_extra_stats;
 struct stmmac_priv;
 struct stmmac_safety_stats;
+struct stmmac_fpe_cfg;
+enum stmmac_mpacket_type;
 struct dma_desc;

Other than that the patch looks good:
