net: phy: extract pause mode

2019-10-05T01:11:08+00:00

Extract the update of phylib's software pause mode state from genphy_read_status(), so that we can re-use this functionality with PHYs that have alternative ways to read the negotiation results. Tested-by: tinywrkb Reviewed-by: Andrew Lunn Signed-off-by: Russell King Signed-off-by: David S. Miller

net: phy: add phy_speed_down_core and phy_resolve_min_speed

2019-08-14T00:14:06+00:00

phy_speed_down_core provides most of the functionality for phy_speed_down. It makes use of new helper phy_resolve_min_speed that is based on the sorting of the settings[] array. In certain cases it may be helpful to be able to exclude legacy half duplex modes, therefore prepare phy_resolve_min_speed() for it. v2: - rename __phy_speed_down to phy_speed_down_core Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: Jakub Kicinski

net: phy: add __set_linkmode_max_speed

2019-08-14T00:14:06+00:00

We will need the functionality of __set_linkmode_max_speed also for linkmode bitmaps other than phydev->supported. Therefore split it. v2: - remove unused parameter from __set_linkmode_max_speed Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: Jakub Kicinski

net: phy: add phy_modify_paged_changed

2019-08-12T04:24:32+00:00

Add helper function phy_modify_paged_changed, behavios is the same as for phy_modify_changed. Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: Add support for 100BaseT1 and 1000BaseT1

2019-05-23T00:46:28+00:00

Add link modes for 100Mbps and 1Gbps over a single pair. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: improve pause handling

2019-05-04T04:47:55+00:00

When probing the phy device we set sym and asym pause in the "supported" bitmap (unless the PHY tells us otherwise). However we don't know yet whether the MAC supports pause. Simply copying phy->supported to phy->advertising will trigger advertising pause, and that's not what we want. Therefore add phy_advertise_supported() that copies all modes but doesn't touch the pause bits. In phy_support_(a)sym_pause we shouldn't set any bits in the supported bitmap because we may set a bit the PHY intentionally disabled. Effective pause support should be the AND-combined PHY and MAC pause capabilities. If the MAC supports everything, then it's only relevant what the PHY supports. If MAC supports sym pause only, then we have to clear the asym bit in phydev->supported. Copy the pause flags only and don't touch the modes, because a driver may have intentionally removed a mode from phydev->advertising.

phy: warn if phylib and ethtool PHY mode definitions are out of sync

2019-04-14T20:37:06+00:00

If new PHY modes are added people may miss to update all relevant places in the kernel. Therefore add a build bug check for new modes in enum ethtool_link_mode_bit_indices that haven't been added to phylib yet.

net: phy: add support for new modes in phylib

2019-04-14T20:37:06+00:00

Recently new modes have been added to ethtool.h, but the related extension to phylib hasn't been done yet. So add support for these modes. v2: - add missing 100Gbps and 50Gbps modes Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: shrink PHY settings array

2019-04-14T20:37:06+00:00

The definition of array settings[] is quite lengthy meanwhile. Add a macro to shrink the definition. v2: - Fix an indentation issue Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: improve phy_resolve_aneg_linkmode

2019-02-17T23:21:38+00:00

We have the settings array of modes which is sorted based on aneg priority. Instead of checking each mode manually let's simply iterate over the sorted settings. Signed-off-by: Heiner Kallweit Signed-off-by: David S. Miller
