2014-06-08i40e/i40evf: fix TSO accountingJesse Brandeburg2-8/+3
The TSO logic in the transmit path had some assumptions that have been broken now that the kernel can send as much as 32kB in a single skb->frag[.] entry, even on a system with 4kB pages. This fixes the assumptions and allows the kernel to operate as efficiently as possible with both SENDFILE and SEND. In addition, the hardware limit of data contained in a descriptor is changed to the next power of two below where it currently is in order to align to a power of two value, preventing a single byte of data in a descriptor.

2014-06-05i40evf: fix crash when changing ring sizesMitch Williams3-13/+15
i40evf_set_ringparam was broken in several ways. First, it only changed the size of the first ring, and second, changing the ring size would often result in a panic because it would change the count before deallocating resources, causing the driver to either free nonexistent buffers, or leak leftover buffers. Fix this by storing the descriptor count in the adapter structure, and updating the count for each ring each time we allocate them. This ensures that we always free the right size ring, and always end up with the requested count when the device is (re)opened.

git://git.kernel.org/pub/scm/linux/kernel/git/bwh/net-next Ben Hutchings says: ==================== Pull request: Fixes for new ethtool RSS commands This addresses several problems I previously identified with the new ETHTOOL_{G,S}RSSH commands: 1. Missing validation of reserved parameters 2. Vague documentation 3. Use of unnamed magic number 4. No consolidation with existing driver operations I don't currently have access to suitable network hardware, but have tested these changes with a dummy driver that can support various combinations of operations and sizes, together with (a) Debian's ethtool 3.13 (b) ethtool 3.14 with the submitted patch to use ETHTOOL_{G,S}RSSH and minor adjustment for fixes 1 and 3. v2: Update RSS operations in vmxnet3 too ==================== Signed-off-by: David S.

2014-05-29i40evf: don't use RESETTING state during reinitMitch Williams1-2/+0
The RESETTING state means that a Catastrophic Hardware Bad Thing is happening and the driver need to tiptoe around and not use the admin queue or registers or anything like that. On the other hand, a reinit is no big deal and we can use the admin queue, and we should. So don't set the state to RESETTING here. This fixes a Tx hang and FW crash that happens after setting the MTU on a VF.
