* be2net: re-enable vlan filtering mode asapKalesh AP2014-07-02
| | | | | | | | | | | While adding vlans, when the HW limit of vlan filters is reached, the driver enables vlan promiscuous mode. Similarily, while removing vlans, the driver must re-enable HW filtering as soon as the number of vlan filters is within the HW limit.

* be2net: create optimal number of queues on SR-IOV configVasundhara Volam2014-07-02
| | | | | | | | | | | | | | | If SR-IOV is enabled in the adapter, the FW distributes queue resources evenly across the PF and it's VFs. If the user is not interested in enabling VFs, the queues set aside for VFs are wasted. This patch adds support for the PF driver to re-configure the resource distribution in FW based on the number of VFs enabled by the user. This also allows for supporting RSS queues on VFs, when less number of VFs are enabled per PF. When maximum number of VFs are enabled, each VF typically gets only one RXQ.

Shannon adds the Base Address High and Low to the admin queue structure to simplify the logic in the configuration routines. Also adds code to clear all queues and interrupts to help clean up after a PXE or other early boot activity. Kevin fixes mask assignment value since -1 cannot be used for unsigned integer types. Mitch fixes an issue where in some circumstances the reply from the PF would come back before we were able to properly modify the admin queue pending and required flags. This would mess up the flags and put the driver in an indeterminate state, so fix this by simply setting the flags before sending the request to the admin queue. Also changes the branding string for i40evf to reduce confusion and to match up with our other marketing materials. Kamil adds a new variable defining admin send queue (ASQ) command write back timeout to allow for dynamic modification of this timeout. Anjali fix a bug in the flow director filter replay logic, so that we call a replay after a sideband reset correctly. Jesse adds code to initialize all members of the context descriptor to prevent possible stale data. Christopher fixes i40e to prevent writing to reserved bits, since the queue index is only 0-127. Jacob removes the unneeded header export.h from the i40e PTP code. Fixes ixgbe PTP code where the PPS signal was not correct, as it generates a one half HZ clock signal, it only generates one level change per second.

| * i40evf: set flags before sending messageMitch Williams2014-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some circumstances, the firmware could beat us to the punch, and the reply from the PF would come back before we were able to properly modify the aq_pending and aq_required flags. This would mess up the flags and put the driver in an indeterminate state, much like Schrödinger's cat. However, unlike the cat, the driver is definitely dead. To fix this, simply set the flags before sending the request to the AQ. This way, it won't matter if the interrupt comes back too soon.

A VF in a VM running that distribution over a new hypervisor will access incorrect addresses when trying to transmit packets, causing an attention in the hypervisor and making that VF inactive until FLRed. The driver in the VM has to ne upgraded [no real way to overcome this], but due to the HW attention currently arising upgrading the driver in the VM would not suffice [since the VF needs also be FLRed if the previous driver was already loaded]. This patch causes the PF to fail the acquire message from a VF running an old problematic driver; The VF will then gracefully fail it's probe preventing the HW attention [and allow clean upgrade of driver in VM].

Kamil provides a cleanup patch to i40e where we do not need to acquire the NVM for shadow RAM checksum calculation, since we only read the shadow RAM through SRCTL register. Paul provides a fix for handling HMC for big endian architectures for i40e and i40evf. Mitch provides four cleanup and fixes for i40evf. Fix an issue where if the VF driver fails to complete early init, then rmmod can cause a softlock when the driver tries to stop a watchdog timer that never got initialized. So add a check to see if the timer is actually initialized before stopping it. Make the function i40evf_send_api_ver() return more useful information, instead of just returning -EIO by propagating firmware errors back to the caller and log a message if the PF sends an invalid reply. Fix up a log message that was missing a word, which makes the log message more readable. Fix an initialization failure if many VFs are instantiated at the same time and the VF module is autoloaded by simply resending firmware request if there is no response the first time. Jacob does a rename of the function i40e_ptp_enable() to i40e_ptp_feature_enable(), like he did for ixgbe, to reduce possible confusion and ambugity in the purpose of the function. Does follow on PTP work on i40e, like he did for ixgbe, by breaking the PTP hardware control from the ioctl command for timestamping mode. By doing this, we can maintain state about the 1588 timestamping mode and properly re-enable to the last known mode during a re-initialization of 1588 bits. Anjali cleans up the i40e driver where TCP-IPv4 filters were being added twice, which seems to be left over from when we had to add two PTYPEs for one filter. Fixes the flow director sideband logic to detect when there is a full flow director table. Also fixes the programming of FDIR where a couple of fields in the descriptor setup that were not being programmed, which left the opportunity for stale data to be pushed as part of the descriptor next time it was used. ==================== Signed-off-by: David S.

| * i40e: Fix the FD sideband logic to detect a FD table full conditionAnjali Singhai Jain2014-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware does not have a way of telling a PF how much of the global shared FD table space is still available or is consumed. Previously, every PF but PF0 would think there was still space available when there wasn't. The PFs would continue to try to add filters and fail. With this new logic if a filter programming error is detected we just check if we are close to the guaranteed space full and that can be used as a hint to say, there might not be space and we should turn off the features. This way we can turn off the feature in SW for all PFs in time.

| * i40e: Avoid adding the TCP-IPv4 filter twiceAnjali Singhai Jain2014-06-26
| | | | | | | | | | | | | | | | | | | | | | There wasn't a need to play the logic twice, it seems like a left over from when we had to add two PTYPEs for one filter. There should be no change in the number of filters that actually got added to the hardware.

| * i40e: only create PTP device node onceJacob Keller2014-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently every time we run through the i40e_ptp_init routine, we create a new device node. This function is called by i40e_reset_and_rebuild which is used to handle reset of the device. Even though the 1588 registers only get cleared on a GLOBAL reset, this function is still called to handle a CORE reset. This causes a leak of PTP device nodes at every reset. To fix this, break PTP device clock node creation out of i40e_ptp_init, and only call this if we don't already have a device created. Further invocation of i40e_ptp_init will not generate new PTP devices. Instead, only the necessary work required to reconfigure 1588 will be done. This change also fixes an issue where a reset can cause the device to forget it's timestamp configuration, and revert to the default mode.

| * i40e: don't store user requested mode until we've validated itJacob Keller2014-06-26
| | | | | | | | | | | | | | | | | | | | This patch prevents the SIOCGHWTSTAMP ioctl from possibly returning bad data, by not permanently storing the setting into the private structure until after we've finished validating that we can support it.

| * i40e: break PTP hardware control from ioctl command for timestamp modeJacob Keller2014-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch facilitates future work by breaking the PTP hardware control bits out of the i40e_set_ts_config function. By doing this, we can maintain state about the 1588 timestamping mode and properly re-enable to the last known mode during a re-initialize of 1588 bits. This patch also modifies i40e_ptp_init to call the i40e_ptp_set_timestamp_mode during the reconfiguration process. A future patch will ensure that the hwtstamp_config structure is not reset during this process, so that timestamp mode will be maintained across a reset.

| * i40evf: resend FW request if no responseMitch Williams2014-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes the firmware will not indicate an error but fail to pass a message between the VF and the PF driver. If this happens, just resend the request. This fixes an initialization failure if many VFs are instantiated at the same time and the VF module is autoloaded.
