| | | | | | | | | | | | | | Fix a panic that would occur in the VF if the PF driver failed or was removed from the host kernel. In this case, the VF driver calls i40evf_close(), but this function does nothing because the driver is in the resetting state. Because of this, the driver doesn't free its irqs and causes a kernel panic when it tries to disable MSI-X.

* i40e/i40evf: fix error checking pathJean Sacren2014-03-311-5/+6
| | | | | | | | | | | | | | | The commit 6494294f277fd ("i40e/i40evf: Use dma_set_mask_and_coherent") uses dma_set_mask_and_coherent() to replace dma_set_coherent_mask() for the benefit of return error. The conversion brings some confusion in error checking as whether against DMA_BIT_MASK(64) or DMA_BIT_MASK(32). For one, if error is zero, the check will be against DMA_BIT_MASK(64) twice. Fix this error checking by binding the check to the pertinent one.

| | | | | | | | | | | | | We need to make sure that we stay away from the cache line where the DD bit (done) may be getting written back for the transmit ring since the hardware may be writing the whole cache line for a partial update.

* i40e/i40evf: i40e implementation for skb_set_hashJesse Brandeburg2014-03-063-2/+400
| | | | | | | | | | | | | | | | | | | | Original comment from Tom Herbert <therbert@google.com> Drivers should call skb_set_hash to set the hash and its type in an skbuff. This patch builds upon Tom's original implementation and adds the L4 type return when we know it is an L4 hash. This requires use of the ptype decoder ring, so enable it.
