2014-05-29i40evf: tweak Tx rate params and de-magic-ifyMitch Williams1-2/+5
In order for the VF to achieve its programmed Tx rate, we need to set the max credits value to 4. While we're at it, get rid of some magic numbers.

2014-05-29i40evf: don't round Tx rate down to 0Mitch Williams1-0/+5
Because the hardware configures VF Tx rates in increments of 50 Mbps, values smaller than that would be rounded down to 0, which was interpreted as no limit at all. Rather than do this, we round up to 50 Mbps and notify the user.

2014-05-23net-next:v4: Add support to configure SR-IOV VF minimum and maximum Tx rate ↵Sucheta Chakraborty3-11/+20
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 Parikh1-0/+2
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.

2014-04-26i40e: fix Timesync Tx interrupt handler codeJacob Keller1-4/+1
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.

2014-04-22i40e/i40evf: add tracking to NVM busy stateShannon Nelson2-0/+24
The NVM updates take some time and are asynchronous actions that signal their completion with an AdminQ event. This code tracks when there is an NVM update outstanding and won't allow a new update command until a completion event is received from the current update.

2014-04-22i40e: Enable VF Tx bandwidth settingMitch Williams4-2/+98
Implement the net device op for Tx bandwidth setting. Setting the Tx bandwidth is done by 'ip link set <PF device> vf <VF num> rate <Tx rate>', with the rate specified in Mbit/sec. The rate setting is displayed with 'ip link show'.

2014-04-22i40e: Reset the VF upon conflicting VLAN configurationGreg Rose1-1/+25
If a host VMM administrator hoses his VF by assigning a port VLAN after it is already up and running with implicit permission to set local VLANs then we print a message warning the host administrator that the VF driver needs to be reloaded. In addition we need to knock the VF offline so that it does not continue to receive traffic not on the port VLAN assigned to it. So we reset the VF. The VF will cease operation and the administrator will be forced to unload and reload the VF driver to make it work again.

2014-04-19i40e: fix TCP flag replication for hardware offloadJesse Brandeburg1-0/+9
As reported by Eric Dumazet, the i40e driver was allowing the hardware to replicate the PSH flag on all segments of a TSO operation. This patch fixes the first/middle/last TCP flags settings which makes the TSO operations work correctly. With this change we are now configuring the CWR bit to only be set in the first packet of a TSO, so this patch also enables TSO_ECN, in order to advertise to the stack that we do the right thing on the wire.
