2023-03-27octeon_ep: poll for control messagesVeerasenareddy Burru
Poll for control messages until interrupts are enabled. All the interrupts are enabled in ndo_open(). Add ability to listen for notifications from firmware before ndo_open(). Once interrupts are enabled, this polling is disabled and all the messages are processed by bottom half of interrupt handler.

2023-03-08octeon_ep: Drop redundant pci_enable_pcie_error_reporting()Bjorn Helgaas
pci_enable_pcie_error_reporting() enables the device to send ERR_* Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Also remove the corresponding pci_disable_pcie_error_reporting() from the driver .remove() path. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver.

2022-11-14octeon_ep: ensure get mac address successfully before eth_hw_addr_set()Ziyang Xuan
octep_get_mac_addr() can fail because send mbox message failed. If this happens, octep_dev->mac_addr will be zero. It should not continue to initialize. Add exception handling for octep_get_mac_addr() to fix it.

2022-11-14octeon_ep: fix potential memory leak in octep_device_setup()Ziyang Xuan
When occur unsupported_dev and mbox init errors, it did not free oct->conf and iounmap() oct->mmio[i].hw_addr. That would trigger memory leak problem. Add kfree() for oct->conf and iounmap() for oct->mmio[i].hw_addr under unsupported_dev and mbox init errors to fix the problem.

octep_get_link_status() can fail because send mbox message failed, then octep_get_link_status() will return ret less than 0. Excute octep_link_up() as long as ret is not equal to 0 in octep_open() now. That is not correct. The value type of link.state is enum octep_ctrl_net_state. Positive value represents up. Excute octep_link_up() when ret is bigger than 0.

When taken, the error handling path does not undo correctly what has already been allocated. Introduce a new loop index, 'j', in order to simplify the error handling path and rewrite part of it.

2022-04-15octeon_ep: Remove custom driver versionLeon Romanovsky
In review comment [1] was pointed that new code is not supposed to set driver version and should rely on kernel version instead. As an outcome of that comment all the dance around setting such driver version to FW should be removed too, because in upstream kernel whole driver will have same version so read/write from/to FW will give same result.
