ethtool: cosmetic: Use ethtool ethtool_cmd_speed API

2011-04-29T21:03:01Z

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 Signed-off-by: David S. Miller

ethtool: Call ethtool's get/set_settings callbacks with cleaned data

2011-04-29T21:01:30Z

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 Signed-off-by: David S. Miller

mdio: Expose pause frame advertising flags to ethtool

2009-10-13T06:59:08Z

In mdio45_ethtool_gset_npage() and mdio45_ethtool_gset(), check MDIO pause frame advertising flags and set the corresponding ethtool flags. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

mdio: Advertise pause (flow control) settings even if autoneg is off

2009-10-13T06:59:07Z

Currently, if pause autoneg is off we do not set either pause advertising flag. If autonegotiation of speed and duplex settings is enabled, there is no way for the link partner to distinguish this from our refusing to use pause frames. We should instead set the advertising flags according to the forced mode so that the link partner can follow our lead. This is consistent with the behaviour of other drivers.

netdev: Remove redundant checks for CAP_NET_ADMIN in MDIO implementations

2009-09-04T03:02:11Z

dev_ioctl() already checks capable(CAP_NET_ADMIN) before calling the driver's implementation of MDIO ioctls. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

mdio: Check MDIO_STAT1_FAULT in mdio45_links_ok()

2009-08-27T00:38:53Z

Some PHYs will report that the link is up even though there is a fault condition. Therefore, check the fault flag too. We must also read STAT2 to reset this flag. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller
