Also - can you describe how you can have multiple netdevs for
the same MAC?

Not netdevs per se, but packets can be redirected to an offload
co-processor.

How is the redirecting configured?


Through filters that can be programmed by the Host cpu or co-processor.

Could you split this patch into basic netdev datapath,
and then as separate patches support for ethtool configuration features,
each with its own patch? This will make it easier for area experts to
review.

The base patch can probably include these:

+	.get_drvinfo		= bcmasp_get_drvinfo,
+	.get_link		= ethtool_op_get_link,
+	.get_link_ksettings	= phy_ethtool_get_link_ksettings,
+	.set_link_ksettings	= phy_ethtool_set_link_ksettings,
+	.get_msglevel		= bcmasp_get_msglevel,
+	.set_msglevel		= bcmasp_set_msglevel,

WoL can be a separate patch:

+	.get_wol		= bcmasp_get_wol,
+	.set_wol		= bcmasp_set_wol,

Stats a separate patch:

+	.get_strings		= bcmasp_get_strings,
+	.get_ethtool_stats	= bcmasp_get_ethtool_stats,
+	.get_sset_count		= bcmasp_get_sset_count,
+	.nway_reset		= phy_ethtool_nway_reset,

Flow steering separate:

+	.get_rxnfc		= bcmasp_get_rxnfc,
+	.set_rxnfc		= bcmasp_set_rxnfc,

EEE separate:

+	.set_eee		= bcmasp_set_eee,
+	.get_eee		= bcmasp_get_eee,

Will do.
