netdev: Remove redundant checks for CAP_NET_ADMIN in MDIO implementations

2009-09-04T03:02:11+00:00

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

phylib: fixes for PHY_RESUMING state changes

2009-07-02T20:16:55+00:00

The PHY_HALTED state disables phydev->link, but the link will not be updated upon entering PHY_RESUMING. Add a call to phy_read_status() to update the link before entering PHY_RUNNING. If the link is not up at this point, enter the PHY_NOLINK state instead. Also, when transitioning from PHY_RESUMING to PHY_RUNNING, calls to netif_carrier_on() and phydev->adjust_link() are missing. Add the calls similar to the other transitions to PHY_RUNNING. Signed-off-by: Wade Farnsworth Acked-by: Andy Fleming Signed-off-by: David S. Miller

phylib: Fix delay argument of schedule_delayed_work

2009-04-16T10:13:07+00:00

The commit a390d1f3 ("phylib: convert state_queue work to delayed_work") missed converting 'expires' value to 'delay' value. Signed-off-by: Atsushi Nemoto Acked-by: Marcin Slusarz Signed-off-by: David S. Miller

phylib: Allow early-out in phy_change

2009-04-13T21:51:23+00:00

Marvell 88E1121R Dual PHY device can be hardware-configured to use shared interrupt pin for both PHY ports. For such PHY configurations using shared PHY interrupt phy_interrupt() handler will also schedule a work for PHY port which didn't cause an interrupt. This patch adds a possibility for PHY drivers to provide did_interrupt() function which reports if the PHY (or a PHY port in a multi-PHY device) generated an interrupt. This function is called in phy_change() as phy_change() shouldn't proceed if it is invoked for a PHY which didn't cause an interrupt. So check for interrupt originator in phy_change() to allow early-out. Signed-off-by: Anatolij Gustschin Signed-off-by: David S. Miller

workqueue: add to_delayed_work() helper function

2009-04-03T02:04:50+00:00

It is a fairly common operation to have a pointer to a work and to need a pointer to the delayed work it is contained in. In particular, all delayed works which want to rearm themselves will have to do that. So it would seem fair to offer a helper function for this operation.

phylib: convert state_queue work to delayed_work

2009-03-13T22:41:19+00:00

It closes a race in phy_stop_machine when reprogramming of phy_timer (from phy_state_machine) happens between del_timer_sync and cancel_work_sync. Without this change it could lead to crash if phy_device would be freed after phy_stop_machine (timer would fire and schedule freed work).

phylib: add mdiobus_{read,write}

2008-10-08T23:38:41+00:00

Add mdiobus_{read,write} routines to allow direct reading/writing of registers on an mii bus without having to go through the PHY abstraction, and make phy_{read,write} use these primitives. Signed-off-by: Lennert Buytenhek Signed-off-by: David S. Miller

phylib: Wake PHY state machine on interrupt

2008-10-08T22:46:57+00:00

This way the phy layer will respond to a change in phy state immediately, instead of up to one second later when the state machine timer runs. Signed-off-by: Trent Piepho Acked-by: Andy Fleming Signed-off-by: David S. Miller

phylib: phy_mii_ioctl() fixes

2008-10-08T22:24:56+00:00

Make the SIOCGMIIPHY case fall through properly (it is supposed to not only return the ID of the default PHY but also to read from that PHY), and make phy_mii_ioctl() return the same error code as generic_mii_ioctl() in case of an unsupported operation.
