2016-02-18i40evf: Update feature flags to reflect newly enabled featuresAlexander Duyck1-4/+19
Recent changes should have enabled support for IPv6 based tunnels and support for TSO with outer UDP checksums. As such we can update the feature flags to reflect that. In addition we can clean-up the flags that aren't needed such as SCTP and RXCSUM since having the bits there doesn't add any value. I also found one spot where we were setting the same flag twice. It looks like it was probably a git merge error that resulted in the line being duplicated. As such I have dropped it in this patch.

2016-02-17i40evf: set adapter state on reset failureMitch Williams1-0/+1
If a reset fails to complete, the driver gets its affairs in order and awaits the cold solace of rmmod. Unfortunately, it was not properly setting the adapter state, which would cause a panic on rmmod, instead of the desired surcease. Set the adapter state to DOWN in this case, and avoid a panic.

2016-02-16i40evf: enable bus master after resetMitch Williams1-0/+1
If the VF is reset via VFLR, the device will be knocked out of bus master mode, and the driver will fail to recover from the reset. Fix this by enabling bus mastering after every reset. In a non-VFLR case, the bus master bit will not be disabled, and this call will have no effect.

2016-02-03i40evf: null out ring pointers on freeMitch Williams1-0/+2
Since we check these ring pointers to make sure we don't double-allocate or double-free the rings, we had better null them out after we free them. In very rare cases this can cause a panic if the driver is removed during reset recovery.

2016-02-03i40evf: allow channel bonding of VFsMitch Williams1-4/+5
In some modes, bonding would not enslave VF interfaces. This is due to bonding calling change_mtu and the immediately calling open. Because of the asynchronous nature of the admin queue mechanism, the VF returns -EBUSY to the open call, because it knows the previous operation hasn't finished yet. This causes bonding to fail with a less-than-useful error message. To fix this, remove the check for pending operations at the beginning of open. But this introduces a new bug where the driver will panic on a quick close/open cycle. To fix that, we add a new driver state, __I40EVF_DOWN_PENDING, that the driver enters when down is called. The driver finally transitions to a fully DOWN state when it receives confirmation from the PF driver that all the queues are disabled. This allows open to complete even if there is a pending mtu change, and bonding is finally happy.

2015-12-03i40e/i40evf: avoid mutex re-initJesse Brandeburg1-0/+10
If the driver were to happen to have a mutex held while the i40e_init_adminq call was called, the init_adminq might inadvertently call mutex_init on a lock that was held which is a violation of the calling semantics. Fix this by avoiding adminq.c code allocating/freeing this memory, and then do the same work only once in probe/remove. Testing Hints (Required if no HSD): for VF, load i40evf in bare metal and echo 32 > sriov_numvfs; echo 0 > sriov_numvfs in a loop. Yes this is a horrible thing to do.

2015-10-16i40evf: relax and stagger init timing a bitMitch Williams1-2/+2
On some devices, in some systems, in some configurations, the VFs would fail to initialize the first time you loaded the driver. To correct this, increase the delay time for the init task slightly, and wait longer before giving up. If we enable VFs and load the VF driver in the same kernel as the PF driver, we can totally overwhelm the PF driver with AQ requests because all of the instances try to initialize at the same time. To help alleviate this, stagger the initial scheduling of the init task using the PCIe function as a multiplier. We mask off the function to only three bits so no instance has to wait too long. With these two changes, initializing 128 VFs on a single device goes from four minutes to just a few seconds.

2015-10-16i40evf: correctly populate vlan_featuresMitch Williams1-1/+4
The vlan_features field was correctly being set to the same value as the netdev features field. However, this was being done before the features were actually being set up, leaving the vlan_features empty. Also, after a reset, vlan_features will be incorrectly assigned the previous netdev feature flags, which can contain VLAN feature bits. This makes the VLAN code angry and will cause a stack dump. To fix these issues, set up the netdev features first, then mask out the VLAN feature bits when assigning vlan_features.
