Subject: [Intel-wired-lan] [PATCH net v2 0/2] iavf: Fix close path on shutdown and remove in iavf driver.

Message-ID: <20220802115142.65176-1-mateusz.palczewski@intel.com> (raw)

From: Slawomir Laba <slawomirx.laba@intel.com>

iavf_shutdown was implementing an incomplete version
of iavf_remove. It misses several calls to the kernel like
iavf_free_misc_irq, iavf_reset_interrupt_capability, iounmap
that might break the system on reboot or hibernation.

Fix a deadlock introduced by commit
974578017fc1f ("iavf: Add waiting so the port is initialized in remove")
due to race condition between iavf_shutdown and iavf_remove, where
iavf_remove stucks forever in while loop since iavf_shutdown already
set __IAVF_REMOVE adapter state.
