* maint: remove / fix many doubled wordsDaniel P. Berrange2015-09-111-1/+1
| | | | | | | | | | | | Many source files have doubled words (eg "the the", "to to", and so on). Most of these can simply be removed, but a couple were actual mis-spellings (eg "to to" instead of "to do"). There was even one triple word score "to to to" :-) Signed-off-by: Daniel P.

* rocker: mark copy-to-cpu pkts as forwarding offloadedScott Feldman2015-07-071-0/+4
| | | | | | | | | | | | | | | | | For pkts copied to the CPU (to be processed by guest driver), mark the Rx descriptor with flag "OFFLOAD_FWD" to indicate device has already forwarded pkt. The guest driver will use this indicator to avoid duplicate forwarding in the guest OS. Examples include bcast/mcast/unknown ucast pkts flooded to bridged ports. We want to avoid both the device and the guest bridge driver flooding these pkts, which would result in duplicates pkts on the wire. Packet sampling, such as sFlow, can also use this technique to mark pkts for the guest OS to record but otherwise drop.

* rocker: Add support for phys nameDavid Ahern2015-06-121-0/+1
| | | | | | | | | | | | | Add ROCKER_TLV_CMD_PORT_SETTINGS_PHYS_NAME to port settings. This attribute exports the port name to the guest OS allowing it to name interfaces with sensible defaults. Mostly done by Scott for phys_id support; adapted to phys_name by David.

* rocker: add register programming guideScott Feldman2015-05-111-0/+1009
This is the register programming guide for the Rocker device. It's intended for driver writers and device writers. It covers the device's PCI space, the register set, DMA interface, and interrupts.
