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.

The SCTP checksum is really a CRC and is very different from the standards 1's complement checksum that serves as the checksum for IP protocols. This offload interface is also very different. Rename NETIF_F_SCTP_CSUM to NETIF_F_SCTP_CRC to highlight these differences. The term CSUM should be reserved in the stack to refer to the standard 1's complement IP checksum.

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.

Instead of awkwardly keeping a fixed array of pointers in the adapter struct and then allocating ring structs individually, just keep a single pointer and allocate a single blob for the arrays. This simplifies code, shrinks the adapter structure, and future-proofs the driver by not limiting the number of rings we can handle.

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.

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.

Shorten up the delays in the init task, allowing the VF driver to initialize faster. This aids performance in load/unload tests and mitigates DMAR errors in VF enable/disable tests with absurdly short delays. In the real world, the VF driver will come up more quickly. The original values were set conservatively based on what we expected from the firmware in terms of performance. Now that the driver is in use and we know how well firmware responds to our requests, we can shorten these delays.
