On some systems there are compatibility issues with ASPM L1.2 and RTL8125, therefore this state is disabled per default. To allow for the L1.2 power saving on not affected systems, Realtek provides vendors that successfully tested ASPM L1.2 the option to flag this state as safe. According to Realtek this flag will be set first on certain Chromebox devices. Suggested-by:

Tobias Waldekranz says: ==================== net/fsl: xgmac_mdio: Preamble suppression and custom MDC frequencies The first patch removes the docs for a binding that has never been supported by the driver as far as I can see. This is a bit of a mystery to me, maybe Freescale/NXP had/has support for it in an internal version? We then start working on the xgmac_mdio driver, converting the driver to exclusively use managed resources, thereby simplifying the error paths. Suggested by Andrew. Preamble suppression is then added, followed by MDC frequency customization. Neither code will change any bits if the corresponding dt properties are not specified, so as to not trample on any setup done by the bootloader, which boards might have relied on up to now. Finally, we document the new bindings. Tested on a T1023 based board. ==================== Signed-off-by: -

This property has never been supported by the driver. The kernel has settled on "clock-frequency" as the standard name for this binding, so once that is supported we will document that instead. Fixes: 7f93c9d9 ("power/fsl: add MDIO dt binding for FMan") Signed-off-by:

Russell King says: ==================== net: mvneta: use .mac_select_pcs() This series converts mvneta to use the .mac_select_pcs() like eventually everything else will be. mvneta is slightly more involved because we need to rearrange the initialisation first to ensure everything required is initialised prior to phylink_create() being called. Tested locally on SolidRun Clearfog. ==================== Signed-off-by: -

Re-order the mvneta initialisation to move devm based resources and easy setup earlier in the probe function. The primary reason for this is to allow us to switch the driver to use phylink's mac_select_pcs() callback. Signed-off-by:

Changes since v3: -Renamed some constants with OHM suffix for clarity Changes since v2: -fixed tabs/spaces issue in one patch Changes since v1: -moved page selection to config_init so it is handled properly after suspend/resume -added explicit check for empty sfp_support bitmask ==================== Signed-off-by: -

Add support for downstream SFP cages for AR8031 and AR8033. This is primarily intended for fiber modules or direct-attach cables, however copper modules which work in 1000Base-X mode may also function. Such modules are allowed with a warning. Signed-off-by:

Previously this driver always forced the copper page to be selected, however for AR8031 in 100Base-FX or 1000Base-X modes, the fiber page needs to be selected. Set the appropriate mode based on the hardware mode_cfg strap selection. Enable the appropriate interrupt bits to detect fiber-side link up or down events. Update config_aneg and read_status methods to use the appropriate Clause 37 calls when fiber mode is in use. Signed-off-by:

Robert Hancock authored
The fix to select the copper page on AR8031 was being done in the probe function rather than config_init, so it would not be redone after resume from suspend. Move this to config_init so it is always redone when needed. Fixes: c329e5af ("net: phy: at803x: select correct page on config init") Signed-off-by:

I forgot tcp had per netns tracking of timewait sockets, and their sysctl to change the limit. After 0dad4087 ("tcp/dccp: get rid of inet_twsk_purge()"), whole struct net can be freed before last tw socket is freed. We need to allocate a separate struct inet_timewait_death_row object per netns. tw_count becomes a refcount and gains associated debugging infrastructure.
