2014-04-01i40e/i40evf: fix error checking pathJean Sacren1-5/+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.

The commit c7d05ca89f8e ("i40e: driver ethtool core") introduced the new function i40e_add_del_fdir_sctpv4() with the kernel doc description a little bit off. The trivial error was copied over to a different file by the commit 17a73f6b1401 ("i40e: Flow Director sideband accounting") most recently.

2014-03-28i40e: eeprom integrity check on load and emprShannon Nelson2-6/+45
The driver needs to verify the eeprom checksum and firmware crc status bits, and shutdown the driver if they fail. This code stops the processing of traffic, but doesn't kill the PF netdev so that the NVMUpdate process should still have a chance at fixing the image. The eeprom is checked on driver load and after an EMP reset, the latter of which should be generated after an NVMUpdate.

Add the actual ndo function, and modify vc_notify_link_state to check the link status of each VF before sending a message in the case when physical link changes state.

2014-03-07i40e/i40evf: carefully fill tx ringJesse Brandeburg1-2/+2
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.

2014-03-07i40e: fix nvm version and remove firmware reportJesse Brandeburg2-14/+7
The driver needs to use the format that the current NVM uses when printing the version of the NVM. It should remain this way from now on forward. The driver was reporting when firmware was less than an expected version number, but this is not a requirement for the product and we print the firmware number at init and in ethtool -i output. Just remove the print.

2014-03-07i40e/i40evf: i40e implementation for skb_set_hashJesse Brandeburg3-2/+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.
