2015-04-03mvneta: implement SGMII-based in-band link state signalingStas Sergeev1-11/+95
When MDIO bus is unavailable (common setup for SGMII), the in-band signaling must be used to correctly track link state. This patch enables the in-band status delivery for link state changes, namely: - link up/down - link speed - duplex full/half fixed_phy_update_state() is used to update phy status.

2015-04-03add fixed_phy_update_state() - update state of fixed_phyStas Sergeev1-0/+29
Currently fixed_phy uses a callback to periodically poll the link state. This patch adds the fixed_phy_update_state() API. It solves the following problems: - On link state interrupt, MAC driver can't update status. Instead it needs to provide the callback to periodically query the HW about the link state. It is more efficient to update status after interrupt. - The callback needs to be unregistered before phy_disconnect(), or otherwise it will be called with net_dev==NULL. phy_disconnect() does not have enough info to unregister the callback automatically. - The callback needs to be registered before of_phy_connect() to avoid running with outdated state, but of_phy_connect() returns the phy_device pointer, which is needed to register the callback. Registering it before of_phy_connect() will therefore require a hack to get the pointer earlier. Overall, this addition makes the subsequent patch that implements SGMII link status for mvneta, much cleaner.

2015-04-03i40e: Communicate VSI id in place of VSI index to the VFsAnjali Singhai Jain4-53/+76
This does not affect the Virtual channel API as such but it changes the meaning of what is communicated to the VSI resource struct as vsi_id. Earlier vsi_idx was being passed in, which was the index in the PF's VSI array. Now we pass vsi_id as communicated by the FW to the driver. This will help with future expansion of VF and FW communication. With this in place now the VF and Virtual channel driver change to move over to VSI id use is complete and is validated.
