2014-06-08i40e/i40evf: Clean up a few thingsAkeem G Abodunrin
1. There is no ixgbe_watchdog_task function in the driver, so change the comment to the correct function name, i40e_watchdog_subtask. 2. Remove num_msix_entries from interrupt set_up routine because it is never used. 3. Remove some TBD comments that are not needed.

2014-06-08i40e/i40evf: fix rx descriptor statusJesse Brandeburg
As reported by Eric Dumazet, the driver is not masking the right bits in the receive descriptor before it starts checking them. This patch extends the mask to allow for the right bits to be checked, and fixes the issue permanently via a define.

2014-06-06i40e: remove irqs only when they are set upShannon Nelson
Use an extra state variable to keep track of when the IRQs are fully set up. This keeps us from trying to unhook IRQs that already were left unhooked in a failed reset recovery, e.g. when firmware is broken.

2014-06-06i40e: don't remove HMC that doesn't existShannon Nelson
If a reset recovery failed (e.g. firmware is broken), the HMC space won't get set up. We don't need to try to delete it if it didn't get set up. This stops some needless error messages when we already know we need to just tear things down.

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.

2014-05-21i40e: fix passing wrong error code to i40e_open()Jean Sacren
The commit 6c167f582ea9 ("i40e: Refactor and cleanup i40e_open(), adding i40e_vsi_open()") introduced a new function i40e_vsi_open() with the regression by a typo. Due to the commit, the wrong error code would be passed to i40e_open(). Fix this error in i40e_vsi_open() by turning the macro into a negative value so that i40e_open() could return the pertinent error code correctly.

2014-05-21i40e: Check PCI_IOV config to avoid compile errorGreg Rose
The call to i40e_alloc_vfs needs to be wrapped in CONFIG_PCI_IOV because the function itself is wrapped in the same conditional compile block.

2014-05-21i40e: remove Tx work for ptpJesse Brandeburg
The previous removal of the PTP Tx work functionality was incomplete as noted by Jake Keller. This removal allows us to rely on the Tx timesync interrupt.

2014-05-21i40e: Don't disable SR-IOV when VFs are assignedMitch Williams
When VFs are assigned to active VMs and we disable SR-IOV out from under them, bad things happen. Currently, the VM does not crash, but the VFs lose all resources and have no way to get them back. Add an additional check for when the user is disabling through sysfs, and add a comment to clarify why we check twice.

2014-05-21i40e: remove hardcode of stats struct size in ethtoolShannon Nelson
Base the queue stats length on the queue stats struct rather than assuming it is 2 fields. This is in prep for adding data fields which are configuration dependent.

2014-05-21i40e/i40evf: control auto ITR through ethtoolMitch Williams
For all of our supported kernels, ethtool allows us to directly control adaptive ITR instead of just faking it with an ITR value. Support this capability so that user knows explicitly when ITR is being controlled dynamically. Suggested by Ben Hutchings.

2014-05-21i40e/i40evf: set proper default for ITR registersMitch Williams
Ethtool consistently reports 0 values for our ITR settings because we never actually set them. Fix this by setting the default values to the specified default values.
