Subject: [PATCH net-next v2 3/6] net: fec: remove eee_enabled/eee_active in fec_enet_get_eee()
Date: Sun, 04 Feb 2024 12:13:12 +0000	[thread overview]
Message-ID: <E1rWbN2-002cCh-MY@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <Zb9/O81fVAZw4ANr@shell.armlinux.org.uk>

fec_enet_get_eee() sets edata->eee_active and edata->eee_enabled from
its own copy, and then calls phy_ethtool_get_eee() which in turn will
call genphy_c45_ethtool_get_eee().

genphy_c45_ethtool_get_eee() will overwrite eee_enabled and eee_active
with its own interpretation from the PHYs settings and negotiation
result.

Therefore, setting these members in fec_enet_get_eee() is redundant.
Remove this, and remove the setting of fep->eee.eee_active member which
becomes a write-only variable.
