2016-02-17i40e: fix: do not sleep in netdev_opsJesse Brandeburg1-1/+10
The driver was being called by VLAN, bonding, teaming operations that expected to be able to hold locks like rcu_read_lock(). This causes the driver to be held to the requirement to not sleep, and was found by the kernel debug options for checking sleep inside critical section, and the locking validator.

Shannon adds flags to MAC allocation requests to signify that the MAC VLAN filters should come from the shared resource pool. Added a new "set switch config" admin queue command and the new Cisco VXLAN-GPE cloud tunnel type for the admin queue commands. Added more detail to the NVM update debug message in order to see the full ethtool request data. Also added a few more bits of netdev data into the debugfs output for dump VSI. Pandi fixes the width of two datatypes which were being declared a different size from what they are assigned. Anjali fixes an issue where we were not doing write-back on interrupt throttle for legacy case in x722. Mitch adds a counter for ARQ overflows since sometimes an ever-growing number indicates that something bad is happening. Also added 20G speed for Tx bandwidth calculations. Jesse refactors the DCB function based on a community suggestion to change the multi-level if statement into a switch statement.

2016-02-17net: ixgbe: add support for tc_u32 offloadJohn Fastabend3-30/+213
This adds initial support for offloading the u32 tc classifier. This initial implementation only implements a few base matches and actions to illustrate the use of the infrastructure patches. However it is an interesting subset because it handles the u32 next hdr logic to correctly map tcp packets from ip headers using the ihl and protocol fields. After this is accepted we can extend the match and action fields easily by updating the model header file. Also only the drop action is supported initially. Here is a short test script, #tc qdisc add dev eth4 ingress #tc filter add dev eth4 parent ffff: protocol ip \ u32 ht 800: order 1 \ match ip dst 15.0.0.1/32 match ip src 15.0.0.2/32 action drop <-- hardware has dst/src ip match rule installed --> #tc filter del dev eth4 parent ffff: prio 49152 #tc filter add dev eth4 parent ffff: protocol ip prio 99 \ handle 1: u32 divisor 1 #tc filter add dev eth4 protocol ip parent ffff: prio 99 \ u32 ht 800: order 1 link 1: \ offset at 0 mask 0f00 shift 6 plus 0 eat match ip protocol 6 ff #tc filter add dev eth4 parent ffff: protocol ip \ u32 ht 1: order 3 match tcp src 23 ffff action drop <-- hardware has tcp src port rule installed --> #tc qdisc del dev eth4 parent ffff: <-- hardware cleaned up --> Signed-off-by: John Fastabend <[email protected]> Acked-by: Jamal Hadi Salim <[email protected]> Signed-off-by: David S.

2016-02-17net: ixgbe: add minimal parser details for ixgbeJohn Fastabend1-0/+112
This adds an ixgbe data structure that is used to determine what headers:fields can be matched and in what order they are supported. For hardware devices this can be a bit tricky because typically only pre-programmed (firmware, ucode, rtl) parse graphs will be supported and we don't yet have an interface to change these from the OS. So its sort of a you get whatever your friendly vendor provides affair at the moment. In the future we can add the get routines and set routines to update this data structure. One interesting thing to note here is the data structure here identifies ethernet, ip, and tcp fields without having to hardcode them as enumerations or use other identifiers.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2016-02-15 This series contains updates to igb only. Shota Suzuki cleans up unnecessary flag setting for 82576 in igb_set_flag_queue_pairs() since the default block already sets IGB_FLAG_QUEUE_PAIRS to the correct value anyways, so the e1000_82576 code block is not necessary and we can simply fall through. Then fixes an issue where IGB_FLAG_QUEUE_PAIRS can now be set by using "ethtool -L" option but is never cleared unless the driver is reloaded, so clear the queue pairing if the pairing becomes unnecessary as a result of "ethtool -L". Mitch fixes the igbvf from giving up if it fails to get the hardware mailbox lock. This can happen when the PF-VF communication channel is heavily loaded and causes complete communications failure between the PF and VF drivers, so add a counter and a delay so that the driver will now retry ten times before giving up on getting the mailbox lock. The remaining patches in the series are from Alex Duyck, starting with the cleaning up code that sets the MAC address. Then refactors the VFTA and VLVF configuration, to simplify and update to similar setups in the ixgbe driver. Fixed an issue were VLANs headers size was being added to the value programmed into the RLPML registers, yet these registers already take into account the size of the VLAN headers when determining the maximum packet length, so we can drop the code that adds the size to the RLPML registers. Cleaned up the configuration of the VF port based VLAN configuration. Also fixed the igb driver so that we can fully support SR-IOV or the recently added NTUPLE filtering while allowing support for VLAN promiscuous mode.

2016-02-15igb: Add workaround for VLAN tag stripping on 82576Alexander Duyck2-12/+16
There was a workaround partially implemented for the 82576 that is needed in order for VLAN tag stripping to function correctly. The original code had side effects that would make it so the workaround was active on all MACs. I have updated the code so that the workaround is enabled, but limited to the 82576, or activated if we exceed the available unicast addresses. The workaround has a side effect of mirroring all of the traffic outgoing from the VFs back to the PF. As such it is not recommended to use the 82576 in promiscuous mode as it will take a performance hit, though this is now consistent with the performance as seen on the out-of-tree igb driver. I also limited the scope of the UTA bits all being set to only when the VMOLR register is enabled. This should limit the effects of the UTA register so that we don't pick up any excess traffic unless promiscuous mode has been enabled on the PF, whereas before the PF would have ended up in something equivalent to unicast promiscuous mode with VLAN filtering otherwise.

2016-02-15igb: Remove unnecessary flag setting in igb_set_flag_queue_pairs()Shota Suzuki1-8/+0
If VFs are enabled (max_vfs >= 1), both max_rss_queues and adapter->rss_queues are set to 2 in the case of e1000_82576. In this case, IGB_FLAG_QUEUE_PAIRS is always set in the default block as a result of fall-through, thus setting it in the e1000_82576 block is not necessary.

2016-02-11ixgbe: bulk free SKBs during TX completion cleanup cycleJesper Dangaard Brouer1-3/+3
There is an opportunity to bulk free SKBs during reclaiming of resources after DMA transmit completes in ixgbe_clean_tx_irq. Thus, bulk freeing at this point does not introduce any added latency. Simply use napi_consume_skb() which were recently introduced. The napi_budget parameter is needed by napi_consume_skb() to detect if it is called from netpoll.
