net: mii: Fix the Speed display when the network cable is not connected

2025-01-20T20:02:38+00:00

Two different models of usb card, the drivers are r8152 and asix. If no network cable is connected, Speed = 10Mb/s. This problem is repeated in linux 3.10, 4.19, 5.4, 6.12. This problem also exists on the latest kernel. Both drivers call mii_ethtool_get_link_ksettings, but the value of cmd->base.speed in this function can only be SPEED_1000 or SPEED_100 or SPEED_10. When the network cable is not connected, set cmd->base.speed =SPEED_UNKNOWN.

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: Report advertised link capabilities when autonegotiation is off

2020-10-30T02:00:46+00:00

Unify the set of information returned by mii_ethtool_get_link_ksettings(), mii_ethtool_gset() and phy_ethtool_ksettings_get(). Make the mii_*() functions report advertised settings when autonegotiation if disabled.

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

net: mii: report 0 for unknown lp_advertising

2016-11-10T01:26:58+00:00

The newly introduced mii_ethtool_get_link_ksettings function sets lp_advertising to an uninitialized value when BMCR_ANENABLE is not set: drivers/net/mii.c: In function 'mii_ethtool_get_link_ksettings': drivers/net/mii.c:224:2: error: 'lp_advertising' may be used uninitialized in this function [-Werror=maybe-uninitialized] As documented in include/uapi/linux/ethtool.h, the value is expected to be zero when we don't know it, so let's initialize it to that.

net: mii: add generic function to support ksetting support

2016-11-02T19:17:09+00:00

The old ethtool api (get_setting and set_setting) has generic mii functions mii_ethtool_sset and mii_ethtool_gset. To support the new ethtool api ({get|set}_link_ksettings), we add two generics mii function mii_ethtool_{get|set}_link_ksettings_get. Signed-off-by: Philippe Reynes Signed-off-by: David S. Miller

mii: Handle link state changes for forced modes in mii_check_media()

2015-01-19T20:43:42+00:00

mii_check_media() does not update the link (carrier) state or log link changes when the link mode is forced. Drivers using the mii library must do this themselves, but most of them do not. Instead of changing them all, provide a sensible default behaviour similar to mii_check_link() when the mode is forced. via-rhine depends on it being a no-op in this case, so make its call to mii_check_media() conditional.

Add comments for ethtool_cmd::phy_address and ethtool_cmd::mdio_support, and definitions of the flags currently used in mdio_support. In the mdio library, assert that its own flags continue to match those in the ethtool interface. In the mii library, use the ethtool flag definition and stop including .
