net: dsa: b53: unexport and move b53_eee_enable_set()

2024-02-09T03:03:46Z

After commit f86ad77faf24 ("net: dsa: bcm_sf2: Utilize b53_{enable, disable}_port"), bcm_sf2.c no longer calls b53_eee_enable_set(), and all its callers are in b53_common.c. We also need to move it, because it is called within b53_common.c before its definition, and we want to avoid forward declarations.

net: dsa: b53: remove eee_enabled/eee_active in b53_get_mac_eee()

2024-02-07T17:03:38Z

b53_get_mac_eee() sets both eee_enabled and eee_active, and then returns zero. dsa_slave_get_eee(), which calls this function, will then continue to call phylink_ethtool_get_eee(), which will return -EOPNOTSUPP if there is no PHY present, otherwise calling 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. Thus, when there is no PHY, dsa_slave_get_eee() will fail with -EOPNOTSUPP, meaning eee_enabled and eee_active will not be returned to userspace. When there is a PHY, eee_enabled and eee_active will be overwritten by phylib, making the setting of these members in b53_get_mac_eee() entirely unnecessary. Remove this code, thus simplifying b53_get_mac_eee().

ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side

2024-01-31T12:30:47Z

In order to pass EEE link modes beyond bit 32 to userspace we have to complement the 32 bit bitmaps in struct ethtool_eee with linkmode bitmaps. Therefore, similar to ethtool_link_settings and ethtool_link_ksettings, add a struct ethtool_keee. In a first step it's an identical copy of ethtool_eee. This patch simply does a s/ethtool_eee/ethtool_keee/g for all users. No functional change intended.

net: dsa: Use conduit and user terms

Use more inclusive terms throughout the DSA subsystem by moving away from "master" which is replaced by "conduit" and "slave" which is replaced by "user". No functional changes.

Since DSA no longer marks anything as phylink-legacy, there is now no need for DSA drivers to set this member to false. Remove all instances of this. Signed-off-by: Russell King (Oracle) Reviewed-by: Florian Fainelli Reviewed-by: Vladimir Oltean Signed-off-by: Paolo Abeni
