* virtio: populate network rings in the probe routine, not openRusty Russell2008-02-041-19/+25
| | | | | | | 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 Russell2008-02-042-24/+20
| | | | | | | | | | | | | | | | 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 Russell2008-02-042-6/+8
| | | | | | | | | 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: remove unused id field from struct virtio_blk_outhdrRusty Russell2008-02-041-2/+0
| | | | | | | This field has been unused since an older version of virtio. Remove it now before we freeze the ABI. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au.
* virtio: clarify NO_NOTIFY flag usageRusty Russell2008-02-043-6/+13
| | | | | | | | | The other side (host) can set the NO_NOTIFY flag as an optimization, to say "no need to kick me when you add things". Make it clear that this is advisory only; especially that we should always notify when the ring is full. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* virtio: Fix vring_init/vring_size to take unsigned longAnthony Liguori2008-02-041-2/+2
| | | | | | | | | | | | | Using unsigned int resulted in silent truncation of the upper 32-bit on x86_64 resulting in an OOPS since the ring was being initialized wrong. Please reconsider my previous patch to just use PAGE_ALIGN(). Open coding this sort of stuff, no matter how simple it seems, is just asking for this sort of trouble.

* virtio: configuration change callbackRusty Russell2008-02-041-0/+3
| | | | | | | | | | Various drivers want to know when their configuration information changes: the balloon driver is the immediate user, but the network driver may one day have a "carrier" status as well. This introduces that callback (lguest doesn't use it yet). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
* virtio: explicit enable_cb/disable_cb rather than callback return.Rusty Russell2008-02-048-25/+35
| | | | | | | | | | 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 Russell2008-02-0411-281/+280
| | | | | | | | | | | | | 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.

* virtio: Implement skb_partial_csum_set, for setting partial csums on ↵Rusty Russell2008-02-043-10/+31
| | | | | | | | | | untrusted packets. Use it in virtio_net (replacing buggy version there), it's also going to be used by TAP for partial csum support. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Acked-by: David S. Miller <davem@davemloft.net>
