As the driver uses GRO and not LRO, LRO settings are ignored anyway and are removed here to avoid confusion. Signed-off-by:

Current enic code only supports ASSOCIATE and DISASSOCIATE port profile operations. This patch adds enic support for port profile PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable of handling port profile requests done in two steps namely PREASSOCIATE_RR and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly from its use as an optimization during VM migration ie, to do resource reservation on destination host before resources on source host are released. PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE, 8021qbh will also need to support VDP commands. In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation this patch also does the below: - Introduces handlers for PORT_REQUEST operations - Moves most of the port profile handling code to new files enic_pp.[ch] - Uses new fw devcmds for port profile operations Signed-off-by:

This patch provides support to the newer version of firmware devcmd CMD_MCPU_FW_INFO that returns additional information (ASIC type and revision) about the underlying hardware. This knowledge is required by the driver to implement any hardware specific features. Signed-off-by:

During a port profile disassociate all address registrations for the interface are blown away from the adapter. This patch resets the driver cache of registered address lists to zero after a port profile disassociate. Signed-off-by:

We believe that our earlier patch for supporting multiple hardware receive queues per enic device requires more internal testing. At this point, we think that it's best to disable the use of multiple receive queues. The current patch provides an effective means for the same. Also, we continue to disallow multiple hardware transmit queues per device. But change the way we enforce this in order to maintain consistency with the way receive queues are handled. Signed-off-by:

enic_get_vf_port returns port profile operation status only if ENIC_SET_APPLIED flag is set. A recent rework of enic_set_port_profile added code to reset this flag on disassociate. As a result of which a client calling enic_get_vf_port to get the status of port profile disassociate will always get a return value of ENODATA. This patch renames ENIC_SET_APPLIED to more appropriate ENIC_PORT_REQUEST_APPLIED and reverts back the recent change so that the flag is set both at associate and disassociate of a port profile.

This patch adds support in enic 802.1Qbh port profile provisioning code to use the mac address set by IFLA_VF_MAC. For now we handle this mac as a special case for a VM mac address sent to us by libvirt. The VM mac address is sent to the switch along with the rest of the port profile provisioning data. This patch also adds calls to register and deregister the mac address during port profile association/deassociation. Signed-off-by:

To make get/set netlink VF_PORT truly symmetrical, we need to keep track of what items are set and only return those items on get. Previously, the driver wasn't differentiating between a set of attr with a NULL string, for example, and not setting the attr at all. We only want to return the NULL string if the attr was actually set with a NULL string. Otherwise, don't return the attr. Signed-off-by:

Add enic ndo_{set|get}_vf_port ops to support setting/getting port-profile for enic dynamic devices. Enic dynamic devices are just like normal enic eth devices except dynamic enics require an extra configuration step to assign a port-profile identifier to the interface before the interface is useable. Once a port-profile is assigned, link comes up on the interface and is ready for I/O. The port-profile is used to configure the network port assigned to the interface. The network port configuration includes VLAN membership, QoS policies, and port security settings typical of a data center network. A dynamic enic initially has a zero-mac address. Before a port-profile is assigned, a valid non-zero unicast mac address should be assign to the dynamic enic interface. Signed-off-by:

The last bit written to a completion descriptor by hardware is the color bit. Driver must read all other descriptor fields only after reading the color bit to avoid reading stale descriptor fields. There is a rmb() after reading the color bit to avoid any compiler/cpu reordering of the reads. The color bit is the generation bit that toggles each pass through the completion descriptor ring.

Fix dev->stop shutdown bug where driver was stopping xmit queue and then disabling intrs. Fix is to disable intrs first and then stop the xmit queue, otherwise an interrupt could cause the queue to be rewoken. Also, no need to explicitly do queue servicing because queues are cleaned and reset back to initial state at end of dev->stop. Servicing queues also had the side-effect of also rewakening the xmit queue, which is not what we want. Signed-off-by:

Bug fix: don't set netdev->name early before netdev registration. Setting netdev->name early with dev_alloc_name() would occasionally cause netdev registration to fail returning error that device was already registered. Since we're using netdev->name to name MSI-X vectors, we now need to move the request_irq after netdev registartion, so move it to ->open. Signed-off-by:
