net: linkmode: add linkmode_fill() helper

2023-11-16T23:45:04Z

Add a linkmode_fill() helper, which will allow us to convert phylink's open coded bitmap_fill() operations. Signed-off-by: Russell King (Oracle) Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

ethtool: untangle the linkmode and ethtool headers

2023-10-20T11:47:33Z

Commit 26c5334d344d ("ethtool: Add forced speed to supported link modes maps") added a dependency between ethtool.h and linkmode.h. The dependency in the opposite direction already exists so the new code was inserted in an awkward place. The reason for ethtool.h to include linkmode.h, is that ethtool_forced_speed_maps_init() is a static inline helper. That's not really necessary.

ethtool: Add forced speed to supported link modes maps

2023-10-18T08:36:35Z

The need to map Ethtool forced speeds to Ethtool supported link modes is common among drivers. To support this, add a common structure for forced speed maps and a function to init them. This is solution was originally introduced in commit 1d4e4ecccb11 ("qede: populate supported link modes maps on module init") for qede driver. ethtool_forced_speed_maps_init() should be called during driver init with an array of struct ethtool_forced_speed_map to populate the mapping. Definitions for maps themselves are left in the driver code, as the sets of supported link modes may vary between the devices.

net: remove linkmode_change_bit()

2022-01-27T13:53:26Z

No callers since v5.7, the initial use case seems pretty esoteric so removing this should not harm the completeness of the API. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

linkmode: introduce linkmode_intersects()

Add a new helper to find intersections between Ethtool link modes, linkmode_intersects(), similar to the other linkmode helpers. Signed-off-by: Alexander Lobakin Signed-off-by: Igor Russkikh Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: add linkmode helper for setting flow control advertisement

2020-02-17T03:39:44Z

Add a linkmode helper to set the flow control advertisement in an ethtool linkmode mask according to the tx/rx capabilities. This implementation is moved from phylib, and documented with an analysis of its shortcomings. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: add helpers to resolve negotiated flow control

2020-02-17T03:39:44Z

Add a couple of helpers to resolve negotiated flow control. Two helpers are provided: - linkmode_resolve_pause() which takes the link partner and local advertisements, and decodes whether we should enable TX or RX pause at the MAC. This is useful outside of phylib, e.g. in phylink. - phy_get_pause(), which returns the TX/RX enablement status for the current negotiation results of the PHY. This allows us to centralise the flow control resolution, rather than spreading it around. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: linkmode: make linkmode_test_bit() take const pointer

2020-02-17T03:39:44Z

linkmode_test_bit() does not modify the address; test_bit() is also declared const volatile for the same reason. There's no need for linkmode_test_bit() to be any different, and allows implementation of helpers that take a const linkmode pointer.

net: mii: Rename mii_stat1000_to_linkmode_lpa_t

2018-12-06T00:26:16Z

Rename mii_stat1000_to_linkmode_lpa_t to mii_stat1000_mod_linkmode_lpa_t to indicate it modifies the passed linkmode bitmap, without clearing any other bits. Add a helper to set/clear bits in a linkmode. Use this helper to ensure bit are clear which the stat1000 indicates should not be set.
