chip->phy_addr_sel_strap is declared as a bool, but is also used as an integer address base. Rename 'phy_addr_sel_strap' to 'phy_addr_base', and change type to int. Signed-off-by: Egil Hjelmeland <privat@egil-hjelmeland.no> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-01-03nfp: flower: implement the PORT_REIFY messageDirk van der Merwe
The PORT_REIFY message indicates whether reprs have been created or when they are about to be destroyed. This is necessary so firmware can know which state the driver is in, e.g. the firmware will not send any control messages related to ports when the reprs are destroyed. This prevents nuisance warning messages printed whenever the firmware sends updates for non-existent reprs.

2018-01-03net: mdio: Only perform gpio reset for PHYsAndrew Lunn
Ethernet switch on the MDIO bus have historically performed their own handling of the GPIO reset line. The resent patch to have the MDIO core handle the reset has broken the switch drivers, in that they cannot claim the GPIO. Some switch drivers need more control over the GPIO line than what the MDIO core provides. So restore the historical behaviour by only performing a reset of PHYs, not switches.

2018-01-03net: phy: marvell: fix paged access racesRussell King
For paged accesses to be truely safe, we need to hold the bus lock to prevent anyone else gaining access to the registers while we modify them. The phydev->lock mutex does not do this: userspace via the MII ioctl can still sneak in and read or write any register while we are on a different page, and the suspend/resume methods can be called by a thread different to the thread polling the phy status. Races have been observed with mvneta on SolidRun Clearfog with phylink, particularly between the phylib worker reading the PHYs status, and the thread resuming mvneta, calling phy_start() which then calls through to m88e1121_config_aneg_rgmii_delays(), which tries to read-modify-write the MSCR register: CPU0 CPU1 marvell_read_status_page() marvell_set_page(phydev, MII_MARVELL_FIBER_PAGE) ... m88e1121_config_aneg_rgmii_delays() set_page(MII_MARVELL_MSCR_PAGE) phy_read(phydev, MII_88E1121_PHY_MSCR_REG) marvell_set_page(phydev, MII_MARVELL_COPPER_PAGE); ... phy_write(phydev, MII_88E1121_PHY_MSCR_REG) The result of this is we end up writing the copper page register 21, which causes the copper PHY to be disabled, and the link partner sees the link immediately go down. Solve this by taking the bus lock instead of the PHY lock, thereby preventing other accesses to the PHY while we are accessing other PHY pages.
