2016-04-28drivers: net: cpsw: use of_phy_connect() in fixed-link caseDavid Rivshin
If a fixed-link DT subnode is used, the phy_device was looked up so that a PHY ID string could be constructed and passed to phy_connect(). This is not necessary, as the device_node can be passed directly to of_phy_connect() instead. This reuses the same codepath as if the phy-handle DT property was used.

2016-04-28drivers: net: cpsw: don't ignore phy-mode if phy-handle is usedDavid Rivshin
The phy-mode emac property was only being processed in the phy_id or fixed-link cases. However if phy-handle was specified instead, an error message would complain about the lack of phy_id or fixed-link, and then jump past the of_get_phy_mode(). This would result in the PHY mode defaulting to MII, regardless of what the devicetree specified.

2016-04-28drivers: net: cpsw: fix segfault in case of bad phy-handleDavid Rivshin
If an emac node has a phy-handle property that points to something which is not a phy, then a segmentation fault will occur when the interface is brought up. This is because while phy_connect() will return ERR_PTR() on failure, of_phy_connect() will return NULL. The common error check uses IS_ERR(), and so missed when of_phy_connect() fails. The NULL pointer is then dereferenced. Also, the common error message referenced slave->data->phy_id, which would be empty in the case of phy-handle. Instead, use the name of the device_node as a useful identifier. And in the phy_id case add the error code for completeness.

2016-04-28drivers: net: cpsw: fix parsing of phy-handle DT property in dual_emac configDavid Rivshin
Commit 9e42f715264ff158478fa30eaed847f6e131366b ("drivers: net: cpsw: add phy-handle parsing") saved the "phy-handle" phandle into a new cpsw_priv field. However, phy connections are per-slave, so the phy_node field should be in cpsw_slave_data rather than cpsw_priv. This would go unnoticed in a single emac configuration. But in dual_emac mode, the last "phy-handle" property parsed for either slave would be used by both of them, causing them both to refer to the same phy_device.

Alex Duyck cleans up the feature flags since they are becoming pretty "massive", the primary change being that we now build our features list around hw_encap_features. Added support for IPIP and SIT offloads, which should improvement in throughput for IPIP and SIT tunnels with the offload enabled. Mitch adds support for configuring RSS on behalf of the VFs, which removes the burden of dealing with different hardware interfaces from the VF drivers and improves future compatibility. Fix to ensure that we do not panic by checking that the vsi_res pointer is valid before dereferencing it, after which we can drink beer and eat peanuts. Shannon does come housekeeping in i40e_add_fdir_ethtool() in preparation for more cloud filter work. Added flexibility to the nvmupdate facility by adding the ability to specify an AQ event opcode to wait on after Exec_AQ request. Michal adds device capability which defines if an update is available and if a security check is needed during the update process. Kamil just adds a device id to support X722 QSFP+ device. Greg fixes an issue where a mirror rule ID may be zero, so do not return invalid parameter when the user passes in a zero for a rule ID. Adds support to steer packets to VSIs by VLAN tag alone while being in promiscuous mode for multicast and unicast MAC addresses.

2016-04-27net: w5100: support W5500Akinobu Mita
This adds support for W5500 chip. W5500 has similar register and memory organization with W5100 and W5200. There are a few important differences listed below but it is still possible to share common code with W5100 and W5200. * W5500 register and memory are organized by multiple blocks. Each one is selected by 16bits offset address and 5bits block select bits. But the existing register access operations take u16 address. This change extends the addess by u32 address and put offset address to lower 16bits and block select bits to upper 16bits. This change also adds the offset addresses for socket register and TX/RX memory blocks to the driver private data structure in order to reduce conditional switches for each chip. * W5500 has the different register offset for socket interrupt mask register. Newly added internal functions w5100_enable_intr() and w5100_disable_intr() take care of the diffrence. * W5500 has the different register offset for retry time-value register. But this register is only used to verify that the reset value is correctly read at initialization. So move the verification to w5100_hw_reset() which already does different things for different chips.

Replace PAGE_SIZE with BNXT_RX_PAGE_SIZE in all appropriate places related to the rx aggregation ring logic. The next patch will add additional logic to divide the page into 32K chunks for aggrgation ring buffers if PAGE_SIZE is bigger than BNXT_RX_PAGE_SIZE.

2016-04-26net/mlx5e: Fix checksum handling for non-stripped vlan packetsSaeed Mahameed
Now as rx-vlan offload can be disabled, packets can be received with vlan tag not stripped, which means is_first_ethertype_ip will return false, for that we need to check if the hardware reported csum OK so we will report CHECKSUM_UNNECESSARY for those packets.

2016-04-26net/mlx5e: Add support for RXALL netdev featureEran Ben Elisha
Introduce new access register named Ports Check Mask Register (PCMR) to control all HW checks on port. With this register, the driver can enable/disable Hardware FCS validation. When RXALL is enabled/disabled using ndo_set_features, enable/disable fcs check at HW. User can change HW configuration using rx-all flag at ethtool.
