* i40e: fix pf reset after offline testShannon Nelson2013-12-161-6/+8
| | | | | | | | | | | | | | | | | | When the ethtool testing starts it sets the I40E_TESTING state bit, which blocks new netdev opens so that things don't get confused, while the testing might be messing with register and other things. Unfortunately, that was keeping the PF resets after the register test from working correctly because the netdev would not get reopened. This patch reorders the tests to put the register test last as it is the only one that needs a reset, and we wait to trigger the reset until after we clear the I40E_TESTING bit.

* i40e: Add support for 64 bit netstatsAlexander Duyck2013-10-091-4/+23
| | | | | | | | | | | | This change brings support for 64 bit netstats to the driver. Previously the stats were 64 bit but highly racy due to the fact that 64 bit transactions are not atomic on 32 bit systems. This change makes is so that the 64 bit byte and packet stats are reliable on all architectures.

* i40e: Move rings from pointer to array to array of pointersAlexander Duyck2013-10-091-20/+20
| | | | | | | | | | | | | | | | Allocate the queue pairs individually instead of as a group. This allows for much easier queue management as it is possible to dynamically resize the queues without having to free and allocate the entire block. Ease statistic collection by treating Tx/Rx queue pairs as a single unit. Each pair is allocated together and starts with a Tx queue and ends with an Rx queue. By ordering them this way it is possible to know the Rx offset based on a pointer to the Tx queue.

* i40e: Move q_vectors from pointer to array to array of pointersAlexander Duyck2013-10-091-2/+2
| | | | | | | | | | Allocate the q_vectors individually. The advantage to this is that it allows for easier freeing and allocation. In addition it makes it so that we could do node specific allocations at some point in the future.

* i40e: Split bytes and packets from Rx/Tx statsAlexander Duyck2013-10-091-9/+5
| | | | | | | | | | | | | | | | | | This makes it so that the Tx and Rx byte and packet counts are separated from the rest of the statistics. This allows for better isolation of these stats when we move them into the 64 bit statistics. Simplify things by re-ordering how the stats display in ethtool. Instead of displaying all of the Tx queues as a block, followed by all the Rx queues, the new order is Tx[0], Rx[0], Tx[1], Rx[1], ..., Tx[n], Rx[n]. This reduces the loops and cleans up the display for testing purposes since it is very easy to verify if flow director is doing the right thing as the Tx and Rx queue pair are shown in pairs.

* i40e: driver ethtool coreJesse Brandeburg2013-09-111-0/+1449
This patch contains the ethtool interface and implementation. The goal in this patch series is minimal functionality while not including much in the way of "set support."
