There are two issues can be reproduced by the following script:
[root at host ~]# cat test-iavf-1.sh
#!/bin/bash
pf_dbsf="0000:40:01.1/0000:41:00.0"
vf0_dbsf="0000:40:01.1/0000:41:02.0"
g_pids=()
function do_set_numvf()
{
echo "set 2 vfs"
echo 2 >/sys/bus/pci/devices/${pf_dbsf}/sriov_numvfs
sleep $((RANDOM%3+1))
echo "set 0 vfs"
echo 0 >/sys/bus/pci/devices/${pf_dbsf}/sriov_numvfs
sleep $((RANDOM%3+1))
}
function do_nic_reset()
{
local nic=$(ls -1 --indicator-style=none /sys/bus/pci/devices/${vf0_dbsf}/net/)
[ -z "$nic" ] && { sleep $((RANDOM%3)) ; return 1; }
ifconfig $nic 192.168.18.5 netmask 255.255.255.0
ifconfig $nic up
echo "set $nic 1 combined"
ethtool -L $nic combined 1
echo "set $nic 4 combined"
ethtool -L $nic combined 4
sleep $((RANDOM%3))
}
function on_exit()
{
local pid
for pid in "${g_pids[@]}"; do
kill -0 "$pid" &>/dev/null && kill "$pid" &>/dev/null
done
g_pids=()
}
trap "on_exit; exit" EXIT
while :; do do_set_numvf ; done &
g_pids+=($!)
while :; do do_nic_reset ; done &
g_pids+=($!)
wait
