2021-08-19net: mii: make mii_ethtool_gset() return voidPavel Skripkin1-5/+1
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 <paskripkin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-10-30net: mii: Report advertised link capabilities when autonegotiation is offŁukasz Stelmach1-9/+11
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.

2016-11-10net: mii: report 0 for unknown lp_advertisingArnd Bergmann1-0/+2
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.

2016-11-02net: mii: add generic function to support ksetting supportPhilippe Reynes1-0/+195
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.

2015-01-19mii: Handle link state changes for forced modes in mii_check_media()Ben Hutchings1-5/+7
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.

2012-03-02ethtool, mdio, mii: Specify MDIO information fields in struct ethtool_cmdBen Hutchings1-2/+2
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 <linux/mdio.h>.

2011-11-22net: Change mii to ethtool advertisement function namesMatt Carlson1-8/+7
This patch implements advice by Ben Hutchings to change the mii side of the function names to look more like the register whose values they convert. New LPA translation functions have been added as well. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2011-11-17net: Add ethtool to mii advertisment conversion helpersMatt Carlson1-38/+10
Translating between ethtool advertisement settings and MII advertisements are common operations for ethernet drivers. This patch adds a set of helper functions that implements the conversion. The patch then modifies a couple of the drivers to use the new functions. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2011-04-30ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny1-6/+9
This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated. Tested: make allyesconfig on x86_64 + e1000e/bnx2x work Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-04-30ethtool: Use full 32 bit speed range in ethtool's set_settingsDavid Decotigny1-6/+7
This makes sure the ethtool's set_settings() callback of network drivers don't ignore the 16 most significant bits when ethtool calls their set_settings().

2011-04-30ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny1-0/+3
This makes sure that when a driver calls the ethtool's get/set_settings() callback of another driver, the data passed to it is clean. This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline. All drivers visible to make allyesconfig under x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-04-17Linux-2.6.12-rc2Linus Torvalds1-0/+398
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
