2015-05-18net: dsa: bcm_sf2: properly propagate carrier down state for MoCAFlorian Fainelli
MoCA interfaces require the use of an user-space daemon (mocad) which will typically use cmd->autoneg to force the link. This is causing other network manager applications not to get proper carrier down notifications because of the following sequence of events: - link down interrupt is received, link is set to 0 by the interrupt handler - fixed_link update callback runs and updates the BMSR register accordingly - PHY library polls the PHY for link status, sees the link is down, proceeds with reporting that - mocad gets notified of the link state and call phy_ethtool_sset() with cmd->autoneg set to the link status (0) - phy_start_aneg() is called at the end of phy_ethtool_sset() and sets the PHY state to PHY_FORCING Just make sure we notify the interface carrier appropriately when we detect that the link is down in our fixed_link update callback. This is made local to the bcm_sf2 driver as the PHY library does the right thing in any case. This is similar to the GENET change introduced in 54d7c01d3ed699cfc213115eaecfe1175cfaff8f ("net: bcmgenet: enable MoCA link state change detection").

2015-05-18hv_netvsc: change member name of struct netvsc_statssixiao@microsoft.com
Currently the struct netvsc_stats has a member s_sync of type u64_stats_sync. This definition will break kernel build as the macro netdev_alloc_pcpu_stats requires this member name to be syncp. (see netdev_alloc_pcpu_stats definition in ./include/linux/netdevice.h) This patch changes netvsc_stats's member name from s_sync to syncp to fix the build break.

This patch fixed the above issue by using per_cpu stats. netvsc_get_stats64() summarizes TX and RX data by iterating over all CPUs to get their respective stats.

2015-05-14be2net: Support for OS2BMC.Venkata Duvvuru
OS2BMC feature will allow the server to communicate with the on-board BMC/idrac (Baseboard Management Controller) over the LOM via standard Ethernet. When OS2BMC feature is enabled, the LOM will filter traffic coming from the host. If the destination MAC address matches the iDRAC MAC address, it will forward the packet to the NC-SI side band interface for iDRAC processing. Otherwise, it would send it out on the wire to the external network. Broadcast and multicast packets are sent on the side-band NC-SI channel and on the wire as well. Some of the packet filters are not supported in the NIC and hence driver will identify such packets and will hint the NIC to send those packets to the BMC. This is done by duplicating packets on the management ring. Packets are sent to the management ring, by setting mgmt bit in the wrb header. The NIC will forward the packets on the management ring to the BMC through the side-band NC-SI channel.

Four minor merge conflicts: 1) qca_spi.c renamed the local variable used for the SPI device from spi_device to spi, meanwhile the spi_set_drvdata() call got moved further up in the probe function. 2) Two changes were both adding new members to codel params structure, and thus we had overlapping changes to the initializer function. 3) 'net' was making a fix to sk_release_kernel() which is completely removed in 'net-next'. 4) In net_namespace.c, the rtnl_net_fill() call for GET operations had the command value fixed, meanwhile 'net-next' adjusted the argument signature a bit.
