2014-06-05i40e: Rework register diagnosticKamil Krawczyk
Register range, being subject to register diagnostic, can vary among different NVMs. We will try to identify the full range and use it for a register test. This is needed to avoid false test results. If we fail to define the proper register range we will test only the first register from that group.

2014-05-29i40e: relax the firmware API version checkShannon Nelson
As long as the Firmware isn't reporting a higher API major version number than what the driver knows about, the driver does not need to worry as much about greater minor numbers. The API changes minor numbers when things get added to the API, but no existing structs or calls are changed. The driver has the option of warning that the minor numbers don't match. This will allow a little more flexibility in handling newer NICs and NVMs in the field.

2014-05-23net-next:v4: Add support to configure SR-IOV VF minimum and maximum Tx rate ↵Sucheta Chakraborty
through ip tool. o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed to have a bandwidth of at least this value. max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth of up to this value. o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced which takes 4 arguments: netdev, VF number, min_tx_rate, max_tx_rate o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler. o Drivers that currently implement ndo_set_vf_tx_rate should now call ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet implemented by driver. o If user enters only one of either min_tx_rate or max_tx_rate, then, userland should read back the other value from driver and set both for IFLA_VF_RATE. Drivers that have not yet implemented IFLA_VF_RATE should always return min_tx_rate as 0 when read from ip tool. o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then IFLA_VF_RATE should override. o Idea is to have consistent display of rate values to user. o Usage example: - ./ip link set p4p1 vf 0 rate 900 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 900 (Mbps), max_tx_rate 900Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 300 min_tx_rate 200 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 300 (Mbps), max_tx_rate 300Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 600 rate 300 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5, tx rate 600 (Mbps), max_tx_rate 600Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: David S.

2014-04-28i40e: Redistribute queue vectors after DCB reconfigurationNeerav Parikh
The queue vectors are originally distributed among the total number of queues that are configured for a given VSI. The number of queues that are configured for a VSI depends on the number of TCs that are enabled for the VSI at VSI setup/creation time. But, the total number of queues that are configured for a VSI may change based on change in the total number of TCs enabled as a result of change in DCB configuration based on DCBX. Hence, it is required for the queue vectors to be redistributed when the total queues that are configured for a given VSI changes. Without redistributing the vectors the queues that are configured for the newly enabled TCs may not be able to do any Tx/Rx.

2014-04-28i40e/i40evf: add driver version string to driver version commandShannon Nelson
The driver version string was added to this struct to be passed down through the firmware to low-level NC-SI functions. We tell the firmware about the length of the ASCII string not counting any terminating null.

2014-04-28i40e: Use port VLAN in MAC/VLAN filter configurationGreg Rose
The function to set the VF MAC address was not taking the port VLAN filter into account when setting/clearing/resetting the VF's host administered MAC address. Be sure to use the port VLAN for VF MAC filtering configurations.

2014-04-28i40e: remove ptp_tx_work timestamp work itemJacob Keller
This patch removes the unnecessary ptp_tx_work item. It conflicts with the interrupt-based handler, and will cause spurious warning messages to be displayed in the kernel log. Since the hardware can properly trigger an interrupt, we do not need to poll for an available timestamp in a work queue any more.

2014-04-26i40e: fix Timesync Tx interrupt handler codeJacob Keller
This patch fixes the PTP Tx timestamp interrupt handler. The original code misinterpreted the interrupt handler design. We were clearing the ena_mask bit for the Timesync interrupts. This is done to indicate that the interrupt will be handled in a scheduled work item (instead of immediately) and that work item is responsible for re-enabling the interrupts. However, the Tx timestamp was being handled immediately and nothing was ever re-enabling it. This resulted in a single interrupt working for the life of the driver. This patch fixes the issue by instead clearing the bit from icr0 which is used to indicate that the interrupt was immediately handled and can be re-enabled right away. This patch also clears up a related issue due to writing the PRTTSYN_STAT_0 register, which was unintentionally clearing the cause bits for Timesync interrupts.

2014-04-23i40e: report VF link state correctlyMitch Williams
Although the driver would correctly allow the VF link state to be controlled by 'ip set link', it would not report it correctly back. Fix this by filling out the appropriate field in the vf info struct.

Use the newer i40e_vsi_open() and i40e_vsi_close() in the FDIR VSI lifetime. This makes sure we're using standard methods for all the VSI open and close paths. This also fixes a memory leak of the FDIR queue buffer info structs across a reset.
