2014-11-13vxlan: Do not reuse sockets for a different address familyMarcelo Leitner
Currently, we only match against local port number in order to reuse socket. But if this new vxlan wants an IPv6 socket and a IPv4 one bound to that port, vxlan will reuse an IPv4 socket as IPv6 and a panic will follow.

2014-11-13net/mlx4_core: Flexible (asymmetric) allocation of EQs and MSI-X vectors for ↵Matan Barak
PF/VFs Previously, the driver queried the firmware in order to get the number of supported EQs. Under SRIOV, since this was done before the driver notified the firmware how many VFs it actually needs, the firmware had to take into account a worst case scenario and always allocated four EQs per VF, where one was used for events while the others were used for completions. Now, when the firmware supports the asymmetric allocation scheme, denoted by exposing num_sys_eqs > 0 (--> MLX4_DEV_CAP_FLAG2_SYS_EQS), we use the QUERY_FUNC command to query the firmware before enabling SRIOV. Thus we can get more EQs and MSI-X vectors per function. Moreover, when running in the new firmware/driver mode, the limitation that the number of EQs should be a power of two is lifted.

2014-11-13smsc911x: power-up phydev before doing a software reset.Enric Balletbo i Serra
With commit be9dad1f9f26604fb ("net: phy: suspend phydev when going to HALTED"), the PHY device will be put in a low-power mode using BMCR_PDOWN if the the interface is set down. The smsc911x driver does a software_reset opening the device driver (ndo_open). In such case, the PHY must be powered-up before access to any register and before calling the software_reset function. Otherwise, as the PHY is powered down the software reset fails and the interface can not be enabled again. This patch fixes this scenario that is easy to reproduce setting down the network interface and setting up again. $ ifconfig eth0 down $ ifconfig eth0 up ifconfig: SIOCSIFFLAGS: Input/output error Signed-off-by: Enric Balletbo i Serra <eballetbo@iseebcn.com> Signed-off-by: David S.

2014-11-13net: generic dev_disable_lro() stacked device handlingMichal Kubeček
Large receive offloading is known to cause problems if received packets are passed to other host. Therefore the kernel disables it by calling dev_disable_lro() whenever a network device is enslaved in a bridge or forwarding is enabled for it (or globally). For virtual devices we need to disable LRO on the underlying physical device (which is actually receiving the packets). Current dev_disable_lro() code handles this propagation for a vlan (including 802.1ad nested vlan), macvlan or a vlan on top of a macvlan. It doesn't handle other stacked devices and their combinations, in particular propagation from a bond to its slaves which often causes problems in virtualization setups. As we now have generic data structures describing the upper-lower device relationship, dev_disable_lro() can be generalized to disable LRO also for all lower devices (if any) once it is disabled for the device itself. For bonding and teaming devices, it is necessary to disable LRO not only on current slaves at the moment when dev_disable_lro() is called but also on any slave (port) added later. v2: use lower device links for all devices (including vlan and macvlan) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Acked-by: Veaceslav Falico <vfalico@gmail.com> Signed-off-by: David S.

2014-11-13net/smsc911x: Fix delays in the PHY enable/disable routinesAlexander Kochetkov
Increased delay in the smsc911x_phy_disable_energy_detect (from 1ms to 2ms). Dropped delays in the smsc911x_phy_enable_energy_detect (100ms and 1ms). The patch affect SMSC LAN generation 4 chips with integrated PHY (LAN9221). I saw problems with soft reset due to wrong udelay timings. After I fixed udelay, I measured the time needed to bring integrated PHY from power-down to operational mode (the time beetween clearing EDPWRDOWN bit and soft reset complete event). I got 1ms (measured using ktime_get). The value is equal to the current value (1ms) used in the smsc911x_phy_disable_energy_detect. It is near the upper bound and in order to avoid rare soft reset faults it is doubled (2ms). I don't know official timing for bringing up integrated PHY as specs doesn't clarify this (or may be I didn't found). It looks safe to drop delays before and after setting EDPWRDOWN bit (enable PHY power-down mode). I didn't saw any regressions with the patch.

2014-11-13net/smsc911x: Fix rare soft reset timeout issue due to PHY power-down modeAlexander Kochetkov
The patch affect SMSC LAN generation 4 chips with integrated PHY (LAN9221). It is possible that PHY could enter power-down mode (ENERGYON clear), between ENERGYON bit check in smsc911x_phy_disable_energy_detect and SRST bit set in smsc911x_soft_reset. This could happen, for example, if someone disconnect ethernet cable between the checks. The PHY in a power-down mode would prevent the MAC portion of chip to be software reseted. Initially found by code review, confirmed later using test case. This is low probability issue, and in order to reproduce it you have to run the script: while true; do ifconfig eth0 down ifconfig eth0 up || break done While the script is running you have to plug/unplug ethernet cable many times (using gpio controlled ethernet switch, for example) until get: [ 4516.477783] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 4516.512207] smsc911x smsc911x.0: eth0: SMSC911x/921x identified at 0xce006000, IRQ: 336 [ 4516.524658] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 4516.559082] smsc911x smsc911x.0: eth0: SMSC911x/921x identified at 0xce006000, IRQ: 336 [ 4516.571990] ADDRCONF(NETDEV_UP): eth0: link is not ready ifconfig: SIOCSIFFLAGS: Input/output error The patch was reviewed by Steve Glendinning and Microchip Team.
