| | * | i40evf: Change vf driver string to reflect all products i40evf supportsCatherine Sullivan2016-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the driver string to 40-10 Gigabit instead of XL710/X710 for X722 and all future products. Also update copyright year in file header.

| | * | i40e: Refactor force_wb and WB_ON_ITR functionality codeAnjali Singhai Jain2016-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the Force-WriteBack functionality in X710/XL710 devices has been moved out of the clean routine and into the service task, we need to make sure WriteBack-On-ITR is separated out since it is still called from clean. In the X722 devices, Force-WriteBack implies WriteBack-On-ITR but without the interrupt, which put the driver into a missed interrupt scenario and a potential tx-timeout report. With this patch, we break the two functions out, and call the appropriate ones at the right place. This will avoid creating missed interrupt like scenarios for X722 devices. Also update copyright year in file headers.

| | * | i40e: add VEB stat control and remove L2 cloud filterShannon Nelson2016-02-17

At the same time, the L2 cloud filtering parameter has been removed as it was never used. Older drivers working with the newer firmware and newer drivers working with older firmware will not run into problems with these bits as the defaults are reasonable and there is no overlap in the bit definitions. Also, newer drivers will be forced to update because of the change in function call parameters, a reminder that the functionality exists. Also update copyright year.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes, ARQ overflows are a big deal and tell us that the firmware/hardware/driver/something is having problems. But normally they're no big deal. To assist in assessing this, add a counter to our Ethtool stats. A handful of ARQ overflows during VF init is no problem. A large, ever-growing number indicates that Something Bad is happening.

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 <john.r.fastabend@intel.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.

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.

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. Also added the ability to use the bridge utility to add a FDB entry for the PF to an igb port. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| | * | igb: Add workaround for VLAN tag stripping on 82576Alexander Duyck2016-02-15

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.
