When e1000e_setup_rx_resources is failed in e1000_open, e1000e_free_tx_resources in "err_setup_rx" segment is executed. "writel(0, tx_ring->head)" statement in e1000_clean_tx_ring in e1000e_free_tx_resources will cause a null poonter dereference(crash), because "tx_ring->head" is only assigned in e1000_configure_tx in e1000_configure, but it is after e1000e_setup_rx_resources. This patch moves head/tail register writing to e1000_configure_tx/rx, which can fix this problem. It is inspired by igb_configure_tx_ring in the igb driver.

When the .remove() callback for a PF is called, SR-IOV support for the device is disabled, which requires unbinding and removing the VFs. The VFs may be in-use either by the host kernel or userspace, such as assigned to a VM through vfio-pci. In this latter case, the VFs may be removed either by shutting down the VM or hot-unplugging the devices from the VM. Unfortunately in the case of a Windows 2012 R2 guest, hot-unplug is broken due to the ordering of the PF driver teardown. Disabling SR-IOV prior to unregister_netdev() avoids this issue.

During driver probing the following code path is triggered. igb_probe ->igb_sw_init ->igb_probe_vfs ->igb_pci_enable_sriov ->igb_sriov_reinit Doing the SR-IOV re-init is not necessary during probing since we're starting from scratch. Here we can call igb_enable_sriov() right away. Running igb_sriov_reinit() during igb_probe() also seems to cause occasional packet loss on some onboard 82576 NICs.

When initializing igb driver (e.g. 82576, I350), IGB_FLAG_QUEUE_PAIRS is set if adapter->rss_queues exceeds half of max_rss_queues in igb_init_queue_configuration(). On the other hand, IGB_FLAG_QUEUE_PAIRS is not set even if the number of queues exceeds half of max_combined in igb_set_channels() when changing the number of queues by "ethtool -L". In this case, if numvecs is larger than MAX_MSIX_ENTRIES (10), the size of adapter->msix_entries[], an overflow can occur in igb_set_interrupt_capability(), which in turn leads to an oops. Fix this problem as follows: - When changing the number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same way as initializing igb driver. - When increasing the size of q_vector, reallocate it appropriately. (With IGB_FLAG_QUEUE_PAIRS set, the size of q_vector gets larger.) Another possible way to fix this problem is to cap the queues at its initial number, which is the number of the initial online cpus. But this is not the optimal way because we cannot increase queues when another cpu becomes online. Note that before commit cd14ef54 ("igb: Change to use statically allocated array for MSIx entries"), this problem did not cause oops but just made the number of queues become 1 because of entering msi_only mode in igb_set_interrupt_capability().

This driver fully supports VF drivers using both the 1.0 and 1.1 versions of the virtual channel API. However, VF drivers using version 1.0 get upset if we provide them with a version other than that, and refuse to play with us. Correct this by checking the VFs API version at the time that we store it off, and provide the correct version number back to the VF so we can all get along.

The most common type of reset that the VF will encounter is a PF reset that cascades down into a VF reset for each VF. In this case, the VF will always be assigned the same VSI and recovery is fairly simple. However, in the case of 'bigger' resets, such as a Core or EMP reset, when the device is reinitialized, it's probable that the VF will NOT get the same VSI. When this happens, the VF will not be able to recover, as it will continue to request resources for its original VSI. Add an extra state to the admin queue state machine so that the driver can re-request its configuration information at runtime. During reset recovery, set this bit in the aq_required field, and fetch the (possibly new) configuration information before attempting to bring the driver back up. Since the driver doesn't know what kind of reset it has encountered, this step is done even for a PF reset, but it doesn't hurt anything - it just gets the same VSI back.

To prepare for the changes coming up in the X722 device and future devices, the virtual channel interface has to change slightly. The VF driver can now report what its capable of supporting, which then informs the PF driver when it sends the configuration information back to the VF. A 1.1 VF driver on a 1.0 PF driver should not send its capabilities. Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect or depend upon receiving the VF capabilities. All other aspects of the API are unchanged.
