2016-06-19net: ethernet: nb8800: use phydev from struct net_devicePhilippe Reynes2-29/+29
The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phydev in the private structure, and update the driver to use the one contained in struct net_device.

2016-06-17net: ethernet: ti: cpsw: remove rx_descs propertyIvan Khoronzhuk4-11/+10
There is no reason in rx_descs property because davinici_cpdma driver splits pool of descriptors equally between tx and rx channels. That is, if number of descriptors 256, 128 of them are for rx channels. While receiving, the descriptor is freed to the pool and then allocated with new skb. And if in DT the "rx_descs" is set to 64, then 128 - 64 = 64 descriptors are always in the pool and cannot be used, for tx, for instance. It's not correct resource usage, better to set it to half of pool, then the rx pool can be used in full. It will not have any impact on performance, as anyway, the "redundant" descriptors were unused. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S.

The last change is that I pulled the rtnl_lock/unlock into the conditional statement for IXGBE_FLAG2_VXLAN_REREG_NEEDED.

2016-06-16net: stmmac: dwmac-rk: keep the PHY up for WoLVincent Palatin1-5/+43
When suspending the machine, do not shutdown the external PHY by cutting its regulator in the mac platform driver suspend code if Wake-on-Lan is enabled, else it cannot wake us up. In order to do this, split the suspend/resume callbacks from the init/exit callbacks, so we can condition the power-down on the lack of need to wake-up from the LAN but do it unconditionally when unloading the module.

2016-06-16net: stmmac: allow to split suspend/resume from init/exit callbacksVincent Palatin1-2/+6
Let the stmmac platform drivers provide dedicated suspend and resume callbacks rather than always re-using the init and exits callbacks. If the driver does not provide the suspend or resume callback, we fall back to the old behavior trying to use exit or init. This allows a specific platform to perform only a partial power-down on suspend if Wake-on-Lan is enabled but always perform the full shutdown sequence if the module is unloaded.

2016-06-15sfc: VLAN filters must only be created if the firmware supports this.Martin Habets2-0/+25
If it is not supported we simply disable the feature. For the feature to work we need firmware filter support for OUTER_VID + LOC_MAC and for OUTER_VID + LOC_MAC_IG. The low-latency firmware can match on OUTER_VID + LOC_MAC but not on OUTER_VID + LOC_MAC_IG. For the capture packet firmware it is the other way around. Only the full-feature variant can match on both combinations. Incorporates a fix by Andrew Rybchenko <Andrew.Rybchenko@oktetlabs.ru> in the net_dev->[hw_]features handling.

2016-06-15sfc: Take mac_lock before calling efx_ef10_filter_table_probeMartin Habets3-2/+11
When trying to enslave an SFC interface to a bond the following BUG_ON was hit: kernel BUG [in ef10.c]! CPU: 0 PID: 4383 Comm: ifenslave Tainted: G ... Call Trace: efx_ef10_filter_add_vlan+0x121/0x180 [sfc] efx_ef10_filter_table_probe+0x2a2/0x4f0 [sfc] efx_ef10_set_mac_address+0x370/0x6d0 [sfc] efx_set_mac_address+0x7d/0x120 [sfc] dev_set_mac_address+0x43/0xa0 bond_enslave+0x337/0xea0 [bonding] This comes from function efx_ef10_filter_vlan_sync_rx_mode. To solve the bug we ensure the mac_lock is taken before calling efx_ef10_filter_add_vlan. But to avoid a priority inversion mac_lock must be taken before filter_sem. To satisfy these requirements we end up taking mac_lock in efx_ef10_vport_set_mac_address, efx_ef10_set_mac_address, efx_ef10_sriov_set_vf_vlan and efx_probe_filters.
