sparc/vio: make remove callback return void
The driver core ignores the return value of struct bus_type::remove() because there is only little that can be done. To simplify the quest to make this function return void, let struct vio_driver::remove() return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and should prevent that future driver authors consider returning an error code.
Note there are two nominally different implementations for a vio bus: one in arch/sparc/kernel/vio.c and the other in arch/powerpc/platforms/pseries/vio.c. This patch only addresses the former.

net: remove 'fallback' argument from dev->ndo_select_queue()
After the previous patch, all the callers of ndo_select_queue() provide as a 'fallback' argument netdev_pick_tx. The only exceptions are nested calls to ndo_select_queue(), which pass down the 'fallback' available in the current scope - still netdev_pick_tx.
We can drop such argument and replace fallback() invocation with netdev_pick_tx(). This avoids an indirect call per xmit packet in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen) with device drivers implementing such ndo. It also clean the code a bit.
Tested with ixgbe and CONFIG_FCOE=m
With pktgen using queue xmit: threads vanilla patched (kpps) (kpps) 1 2334 2428 2 4166 4278 4 7895 8100

This patch makes it so that instead of passing a void pointer as the accel_priv we instead pass a net_device pointer as sb_dev. Making this change allows us to pass the subordinate device through to the fallback function eventually so that we can keep the actual code in the ndo_select_queue call as focused on possible on the exception cases.

sunvnet: add support for IPv6 checksum offloads
The original code didn't handle non-IPv4 packets very well, so the offload advertising had to be scaled back down to just IP. Here we add the bits needed to support TCP and UDP packets over IPv6 and turn the offload advertising back on.

sunvnet: restrict advertized checksum offloads to just IP
As much as we'd like to play well with others, we really aren't handling the checksums on non-IP protocol packets very well. This is easily seen when trying to do TCP over ipv6 - the checksums are garbage.
Here we restrict the checksum feature flag to just IP traffic so that we aren't given work we can't yet do.

ldmvsw: unregistering netdev before disable hardware
When running LDom binding/unbinding test, kernel may panic in ldmvsw_open(). It is more likely that because we're removing the ldc connection before unregistering the netdev in vsw_port_remove(), we set up a window of time where one process could be removing the device while another trying to UP the device. This also sometimes causes vio handshake error due to opening a device without closing it completely. We should unregister the netdev before we disable the "hardware".

ldmvsw: better use of link up and down on ldom vswitch
When an ldom VM is bound, the network vswitch infrastructure is set up for it, but was being forced 'UP' by the userland switch configuration script. When 'UP' but not actually connected to a running VM, the ipv6 neighbor probes fail (not a horrible thing) and start cluttering up the kernel logs. Funny thing: these are debug messages that never actually show up, but we do see the net_ratelimited messages that say N callbacks were suppressed.
This patch defers the netif_carrier_on() until an actual link has been established with the VM, as indicated by receiving an LDC_EVENT_UP from the underlying LDC protocol. Similarly, we take the link down when we see the LDC_EVENT_RESET. Now when we see the ndo_open(), we reset the link to get things talking again.

ldmvsw: disable tso and gso for bridge operations
The ldmvsw driver is specifically for supporting the ldom virtual networking by running in the primary ldom and using the LDC to connect the remaining ldoms to the outside world via a bridge. With TSO and GSO supported while connected the bridge, things tend to misbehave as seen in our case by delayed packets, enough to begin triggering retransmits and affecting overall throughput. By turning off advertised support for TSO and GSO we restore stable traffic flow through the bridge.

ldmvsw: Add ldmvsw.c driver code
Add ldmvsw.c driver
Details:
The ldmvsw driver very closely follows the sunvnet.c code and makes use of the sunvnet_common.c code for core functionality.
A significant difference between sunvnet and ldmvsw driver is sunvnet creates a network interface for each vnet-port *parent* node in the MD while the ldmvsw driver creates a network interface for every vsw-port node in the Machine Description (MD). Therefore the netdev_priv() for sunvnet is a vnet structure while the netdev_priv() for ldmvsw is a vnet_port structure.
Vnet_port structures allocated by ldmvsw have the vsw bit set. When finding the net_device associated with a port, the common code keys off this bit to use either the net_device found in the vnet_port or the net_device in the vnet structure (see the VNET_PORT_TO_NET_DEVICE() macro in sunvnet_common.h). This scheme allows the common code to work with both drivers with minimal changes.
Similar to Xen, network interfaces created by the ldmvsw driver will always have a HW Addr (i.e. mac address) of FE:FF:FF:FF:FF:FF and each will be assigned the devname "vif<cfg_handle>.<port_id>" - where <cfg_handle> and <port_id> are a unique handle/port pair assigned to the associated vsw-port node in the MD.

net: remove 'fallback' argument from dev->ndo_select_queue() After the previous patch, all the callers of ndo_select_queue() provide as a 'fallback' argument netdev_pick_tx. The only exceptions are nested calls to ndo_select_queue(), which pass down the 'fallback' available in the current scope - still netdev_pick_tx. We can drop such argument and replace fallback() invocation with netdev_pick_tx(). This avoids an indirect call per xmit packet in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen) with device drivers implementing such ndo. It also clean the code a bit.
