Drivers: net: hyperv: Negotiate suitable ndis version for offload support

2014-04-11T19:15:12+00:00

Ws2008R2 supports ndis_version 6.1 and 6.1 is the minimal version required for various offloads. Negotiate ndis_version 6.1 when on ws2008r2. Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: David S. Miller

hyperv: Change the receive buffer size for legacy hosts

2014-03-10T20:11:26+00:00

Due to a bug in the Hyper-V host verion 2008R2, we need to use a slightly smaller receive buffer size, otherwise the buffer will not be accepted by the legacy hosts. Signed-off-by: Haiyang Zhang Signed-off-by: David S. Miller

hyperv: Add latest NetVSP versions to auto negotiation

Drivers: net: hyperv: Cleanup the receive path

2014-02-17T21:32:32+00:00

Make the receive path a little more efficient by parameterizing the required state rather than re-establishing that state. Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: David S. Miller

hyperv: Add support for physically discontinuous receive buffer

2014-01-28T00:40:45+00:00

This will allow us to use bigger receive buffer, and prevent allocation failure due to fragmented memory. Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller

drivers/net/*: Fix FSF address in file headers

2013-12-06T17:37:55+00:00

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes.

hyperv: Fix a compiler warning in netvsc_send()

2013-04-29T18:06:32+00:00

Fixed: warning: cast from pointer to integer of different size The Hyper-V hosts always use 64 bit request id. The guests can have 32 or 64 bit pointers which equal to the ulong type size. So we cast it to ulong type. And, assigning 32bit integer to 64 bit variable works fine. The VMBus returns the same id in the completion packet. But the value has no effect on the host side.

hyperv: Fix RNDIS send_completion code path

2013-04-08T16:15:17+00:00

In some cases, the VM_PKT_COMP message can arrive later than RNDIS completion message, which will free the packet memory. This may cause panic due to access to freed memory in netvsc_send_completion(). This patch fixes this problem by removing rndis_filter_send_request_completion() from the code path. The function was a no-op. Reported-by: Long Li Tested-by: Long Li Signed-off-by: Haiyang Zhang Reviewed-by: K. Y. Srinivasan Signed-off-by: David S. Miller

hyperv: Report actual status in receive completion packet
