* 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 3/3] net: phy: realtek: check validity of 10GbE link-partner
|
|
advertisement
|
|
|
|
Only use link-partner advertisement bits for 10GbE modes if they are
|
|
actually valid. Check LOCALOK and REMOTEOK bits and clear 10GbE modes
|
|
unless both of them are set.
