* use interface mode switching only when operating in C45 mode Linux prevents switching the interface mode when using C22 MDIO, hence use rate-adapter mode in case the PHY controlled via C22. * use phy_read_paged where appropriate * use existing generic inline functions to handle 10GbE advertisements instead of redundantly defining register macros in realtek.c which are not actually vendor-specific. * make sure 10GbE advertisement is valid, preventing false-positive warning "Downshift occurred from negotiated speed 2.5Gbps to actual speed 1Gbps, check cabling!" with some link-partners using 1G mode. * Support Link Down Power Saving Mode (ALDPS) Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Subject: [PATCH] net: phy: realtek: support switching between SGMII and
|
|
2500BASE-X for RTL822x series
|
|
|
|
After commit ace6aba ("net: phy: realtek: rtl8221: allow to configure
|
|
SERDES mode"), the rtl8221 phy can work in SGMII and 2500base-x modes
|
|
respectively. So add interface automatic switching for rtl8221 phy to
|
|
match various wire speeds.
