2015-10-15i40e: use priv flags to control flow directorJesse Brandeburg2-0/+15
Some customers wish to be able to control our hardware specific feature called flow director, at runtime. This patch enables ethtool priv flags to control this driver/hardware specific feature. ethtool --set-priv-flags ethX flow-director-atr off NOTE: the ethtool ntuple interface controls the flow-director sideband rules.

2015-10-14i40e/i40evf: Refactor PHY structure and add phy_capabilities enumCatherine Sullivan3-87/+147
Remove unused members in the PHY structure and add a new member to store all the capabilities the PHY has as reported by the FW. This information will help us determine what speeds the device is capable of when link is down. Also add an enum to decode the PHY types the NVM is capable of. Use the phy_types variable to determine what phy types are possible when link is down instead of device id as it will be more accurate. When on a backplane device, we do not support changing any settings, however we should display all the phy_types we are capable of so if we see a backplane dev ID set supported and advertised purely based on the phy_types variable.

2015-10-14i40e/i40evf: Add module_types and update_link_infoCatherine Sullivan5-9/+58
Add a module_types variable to the link_info struct to save the module information from get_phy_capabilities. This information can be used to determine which speeds the module supports. Also add a new function update_link_info which updates the module_types parameter and then calls get_link_info. This function should be called in place of get_link_info so that the module_types variable stays up-to-date with the rest of the link information. The EAS table does not reflect the values that are actually returned, so instead, basing these values on the Ethernet compliance codes specified in table 33 of SFF-8436 as these have been accurate. Use the new variable in ethtool to differentiate between a 10G/1G dual speed fiber module and a 10G only module.

2015-10-14i40e: don't panic on VSI allocation failureMitch Williams1-5/+6
In some circumstances, the firmware may fail to allocate a VSI for a VF. When this happens, the driver does not react well to the bad news and has a panic attack. To fix this problem, check the return value from i40e_alloc_vf_res and don't try to configure the device further if it failed. Additionally, explicitly clear the INIT bit when we free VF resources, so that this bit will be in the proper state in the failure case, and won't blow up elsewhere.

2015-10-08i40e/i40evf: fix unicast mac address addShannon Nelson1-25/+16
When using something like "ip maddr add ..." to add another unicast mac address to the netdev, the mac address comes into the set_rx_mode handler in the multicast list whether it is a unicast or multicast address. This was confusing the code when it was trying to search for addresses that needed to be deleted from the VSI, because it was looking for the VSI unicast address in the netdev unicast list. The result was that a new unicast address would get added to the VSI list and then immediately removed, and would never actually make it down into the hardware. This patch removes the separation from unicast and multicast in the search for filters to be deleted. It also simplifies the logic a little with a jump to the bottom of the loop when an address is found. Now it doesn't matter which netdev list the address is hiding in, we'll check them all.

Previously, the driver could call this function and have only true/false returned, but false could mean multiple things like failure to read or link was down. This change allows the caller to get all return values in the call chain bubbled back to the source, which keeps information about failures from being lost. Also, in some unlikely scenarios, the firmware can become slow to respond to admin queue (AQ) queries for link state. Should the AQ time out, the driver can detect the state and avoid a link change when there may have been none.

2015-10-07i40e/i40evf: fix a potential type compare issueShannon Nelson1-2/+1
Rework an if expression to assure there is no type compare problem between a size and a possible negative number.

2015-10-07i40e: stop VF ringsMitch Williams1-0/+5
Explicitly stop the rings belonging to each VF when disabling SR-IOV. Even though the VFs were gone, and the associated VSIs were removed, the rings were not stopped, and in some circumstances the hardware would continue to access the memory formerly used by the rings, causing memory corruption or DMAR errors, both of which would lead to general malaise of the kernel. To relieve this condition, explicitly stop all the rings associated with each VF before releasing its resources.

2015-10-07i40e: enable WoL operation if config bit show WoL capableShannon Nelson1-2/+7
The driver was disabling Wake-on-LAN by default and waiting for the user to expressly turn it on. This patch has the driver turning on WoL from the start if enabled in the hardware config, which matches the behavior of our other drivers.

2015-10-07i40e/i40evf: set AQ count after memory allocationMitch Williams1-2/+2
The standard way to check if the AQ is enabled is to look at the count field. So we should only set this field after we have successfully allocated memory. To do otherwise is to incite panic among the populace. Signed-off-by: Mitch Williams <mitch.a.williams@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2015-10-05i40e: fix offload of GRE tunnelsJesse Brandeburg1-0/+2
The driver still was not offloading TSO on GRE tunnels because it forgot to set the GSO_GRE flag, causing lots of retransmits. This fixes generic GRE traffic (like a tunnel added like below) whereas before it would get 1Gb/s or less, now on a 10G adapter it gets 8.7Gb/s. ip ad ad 11.1.0.2/24 dev ens2f0 ip l set ens2f0 up ip link add gre2 type gretap remote 11.1.0.1 local 11.1.0.2 dev ens2f0 ip l set gre2 up ip ad ad 192.168.124.2/24 dev gre2 ping 192.168.124.1 netperf -H 192.168.124.1 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2015-10-04i40e/i40evf: grab the AQ spinlocks before clearing registersShannon Nelson1-22/+23
Make sure we have the spinlocks before we clear the ARQ and ASQ management registers. Also, widen the locked portion and make a sanity check earlier in the send function to be sure we're working with safe register values.
