Further cleanup of the vmbus driver: 1) Cleanup the interrupt handler by inlining some code. 2) Ensure message handling is performed on the same CPU that takes the vmbus interrupt. 3) Check for events before messages (from the host). 4) Disable auto eoi for the vmbus interrupt since Linux will eoi the interrupt anyway. 5) Some general cleanup. Regards, K. Y

If we fail to transmit a packet, we assume the queue is full and put the skb into last_xmit_skb. However, if more space frees up before we xmit it, we loop, and the result can be transmitting the same skb twice. Fix is simple: set skb to NULL if we've used it in some way, and check before sending. Signed-off-by: Rusty Russell <rusty at rustcorp.com.au> --- drivers/net/virtio_net.c |

This is a resend of the patches yet to be applied. This patch-set addresses some of the bus/driver model cleanup that Greg sugested over the last couple of days. In this patch-set we deal with the following issues: 1) Cleanup error handling in the vmbus_probe() and vmbus_child_device_register() functions. Fixed a bug in the probe failure path as part of this cleanup. 2) The Windows

This patch-set addresses some of the bus/driver model cleanup that Greg sugested over the last couple of days. In this patch-set we deal with the following issues: 1) Cleanup unnecessary state in struct hv_device and struct hv_driver to be compliant with the Linux Driver model. 2) Cleanup the vmbus_match() function to conform with the Linux Driver model. 3) Cleanup error

From: Mark McLoughlin <markmc at redhat.com> hdr->csum_start is the offset from the start of the ethernet header to the transport layer checksum field. skb->csum_start is the offset from skb->head. skb_partial_csum_set() assumes that skb->data points to the ethernet header - i.e. it computes skb->csum_start by adding the headroom to hdr->csum_start.

This is a rebase/resend of earlier patches. I skipped the pure cosmetic patches for now. Mostly this is consolidation earlier changes, removing dead code etc. The important part is the change for allowing a vmbus channel to get callback directly in interrupt mode; this is necessary for NAPI support.
