* xircom_cb should return NETDEV_TX_BUSY when no descriptors availableErik Mouw2008-02-05
| | | | | | | | | | | | | | | Changes in other networking paths uncovered a bug in the xircom_cb driver which made the kernel spew lots of the following error messages: BUG eth1 code -5 qlen 0 It turned out that the driver returned -EIO when there was no descriptor available for sending packets. It should return NETDEV_TX_BUSY instead. This was discussed on the netdev list before, see http://thread.gmane.org/gmane.linux.network/84603 .

| * virtio: reset functionRusty Russell2008-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A reset function solves three problems: 1) It allows us to renegotiate features, eg. if we want to upgrade a guest driver without rebooting the guest. 2) It gives us a clean way of shutting down virtqueues: after a reset, we know that the buffers won't be used by the host, and 3) It helps the guest recover from messed-up drivers. So we remove the ->shutdown hook, and the only way we now remove feature bits is via reset. We leave it to the driver to do the reset before it deletes queues: the balloon driver, for example, needs to chat to the host in its remove function.

| * virtio: populate network rings in the probe routine, not openRusty Russell2008-02-04
| | | | | | | | | | | | | | Since we want to reset the device to remove them, this is simpler (device is reset for us on driver remove). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
| * virtio: Tweak virtio_net definesRusty Russell2008-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Turn GSO on virtio net into an all-or-nothing (keep checksumming separate). Having multiple bits is a pain: if you can't support something you should handle it in software, which is still a performance win. 2) Make VIRTIO_NET_HDR_GSO_ECN a flag in the header, so it can apply to IPv6 or v4. 3) Rename VIRTIO_NET_F_NO_CSUM to VIRTIO_NET_F_CSUM (ie. means we do checksumming). 4) Add csum and gso params to virtio_net to allow more testing.

| * virtio: Net header needs hdr_lenRusty Russell2008-02-04
| | | | | | | | | | | | | | | | | | It's far easier to deal with packets if we don't have to parse the packet to figure out the header length to know how much to pull into the skb data. Add the field to the virtio_net_hdr struct (and fix the spaces that somehow crept in there). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
| * virtio: explicit enable_cb/disable_cb rather than callback return.Rusty Russell2008-02-04
| | | | | | | | | | | | | | | | | | | | It seems that virtio_net wants to disable callbacks (interrupts) before calling netif_rx_schedule(), so we can't use the return value to do so. Rename "restart" to "cb_enable" and introduce "cb_disable" hook: callback now returns void, rather than a boolean. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
| * virtio: simplify config mechanism.Rusty Russell2008-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously we used a type/len pair within the config space, but this seems overkill. We now simply define a structure which represents the layout in the config space: the config space can now only be extended at the end. The main driver-visible changes: 1) We indicate what fields are present with an explicit feature bit. 2) Virtqueues are explicitly numbered, and not in the config space.
