net: mii: add mii_bmcr_encode_fixed()

2022-06-19T09:38:26+00:00

Add a function to encode a fixed speed/duplex to a BMCR value. Signed-off-by: Russell King (Oracle) Signed-off-by: David S. Miller

net: mii: remove mii_lpa_mod_linkmode_lpa_sgmii()

2022-01-28T14:36:56+00:00

Vladimir points out that since we removed mii_lpa_to_linkmode_lpa_sgmii(), mii_lpa_mod_linkmode_lpa_sgmii() is also no longer called. Suggested-by: Vladimir Oltean Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

mii: remove mii_lpa_to_linkmode_lpa_sgmii()

2022-01-27T13:53:26+00:00

The only caller of mii_lpa_to_linkmode_lpa_sgmii() disappeared in v5.10. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

net: mii: make mii_ethtool_gset() return void

2021-08-19T12:06:53+00:00

mii_ethtool_gset() does not return any errors. Since there are no users of this function that rely on its return value, it can be made void. Signed-off-by: Pavel Skripkin Signed-off-by: David S. Miller

net: mii: add linkmode_adv_to_mii_adv_x()

2020-03-16T00:10:14+00:00

Add a helper to convert a linkmode advertisement to a clause 37 advertisement value for 1000base-x and 2500base-x. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: mii: convert mii_lpa_to_ethtool_lpa_x() to linkmode variant

2020-03-16T00:10:14+00:00

Add a LPA to linkmode decoder for 1000BASE-X protocols; this decoder only provides the modify semantics similar to other such decoders. This replaces the unused mii_lpa_to_ethtool_lpa_x() helper. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

mii: Add helpers for parsing SGMII auto-negotiation

2020-01-06T07:22:32+00:00

Typically a MAC PCS auto-configures itself after it receives the negotiated copper-side link settings from the PHY, but some MAC devices are more special and need manual interpretation of the SGMII AN result. In other cases, the PCS exposes the entire tx_config_reg base page as it is transmitted on the wire during auto-negotiation, so it makes sense to be able to decode the equivalent lp_advertised bit mask from the raw u16 (of course, "lp" considering the PCS to be the local PHY). Therefore, add the bit definitions for the SGMII registers 4 and 5 (local device ability, link partner ability), as well as a link_mode conversion helper that can be used to feed the AN results into phy_resolve_aneg_linkmode.

net: phy: fix write to mii-ctrl1000 register

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

When userspace writes to the MII_ADVERTISE register, we update phylib's advertising mask and trigger a renegotiation. However, writing to the MII_CTRL1000 register, which contains the gigabit advertisement, does neither. This can lead to phylib's copy of the advertisement becoming de-synced with the values in the PHY register set, which can result in incorrect negotiation resolution.

net: mii: Fix PAUSE cap advertisement from linkmode_adv_to_lcl_adv_t() helper

2019-03-28T05:49:06+00:00

With a recent link mode advertisement code update this helper providing local pause capability translation used for flow control link mode negotiation got broken. For eth drivers using this helper, the issue is apparent only if either PAUSE or ASYM_PAUSE is being advertised.
