2013-10-22i40e: check vsi ptrs before dumping themShannon Nelson1-16/+23
Make sure there really are rings and queues before trying to dump information in them. Signed-off-by: Shannon Nelson <[email protected]> Signed-off-by: Jesse Brandeburg <[email protected]> Tested-by: Kavindya Deegala <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>

2013-10-22i40e: fix use of untrusted scalar value warningJesse Brandeburg1-16/+18
This is a fix for an issue reported by coverity, reported by Hannes Frederic Sowa. I'm unable to test if this patch actually fixes the coverity reported issue, feedback is welcome.

2013-10-22i40e: clamp debugfs nvm read commandJesse Brandeburg1-3/+5
This issue was identified by the coverity checker where we were not checking the upper limit on reads, reported by Hannes Frederic Sowa. Implement more specific limits on reads (min 1k, max 4k) Signed-off-by: Jesse Brandeburg <[email protected]> CC: Hannes Frederic Sowa <[email protected]> Tested-by: Kavindya Deegala <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>

2013-10-09i40e: Move rings from pointer to array to array of pointersAlexander Duyck1-95/+100
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.

2013-10-09i40e: Move q_vectors from pointer to array to array of pointersAlexander Duyck1-10/+1
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.

2013-10-09i40e: Split bytes and packets from Rx/Tx statsAlexander Duyck1-4/+4
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.

2013-10-09i40e: Drop unused completed statAlexander Duyck1-2/+1
The Tx "completed" stat was part of the original rewrite for detecting Tx hangs. However some time ago in ixgbe I determined that we could just use the packets stat instead. Since then this stat was removed from ixgbe and it serves no purpose in i40e so it can be dropped.
