iavf: Fix iavf_shutdown to call iavf_remove instead iavf_close
Make the flow for pci shutdown be the same to the pci remove. 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. Implement the call of iavf_remove directly in iavf_shutdown to close this gap. Fixes below error messages (dmesg) during shutdown stress tests - [685814.900917] ice 0000:88:00.0: MAC 02:d0:5f:82:43:5d does not exist for VF 0 [685814.900928] ice 0000:88:00.0: MAC 33:33:00:00:00:01 does not exist for VF 0 Reproduction: 1. Create one VF interface: echo 1 > /sys/class/net/<interface_name>/device/sriov_numvfs 2. Run live dmesg on the host: dmesg -wH 3. On SUT, script below steps into vf_namespace_assignment.sh <#!/bin/sh> // Remove <>. Git removes # line if=<VF name> (edit this per VF name) loop=0 while true; do echo test round $loop let loop++ ip netns add ns$loop ip link set dev $if up ip link set dev $if netns ns$loop ip netns exec ns$loop ip link set dev $if up ip netns exec ns$loop ip link set dev $if netns 1 ip netns delete ns$loop done 4. Run the script for at least 1000 iterations on SUT: ./vf_namespace_assignment.sh Expected result: No errors in dmesg.
