utils_sriov.get_pf_info() cannot get iface name due to prefix '0000:'

[nluu-ampere]

Hi,
I got the issue with this code when run sriov test!

    status, output = utils_misc.cmd_status_output(
        "lspci |awk '/Ethernet/ {print $1}'", shell=True, session=session)
    if status or not output:
        raise exceptions.TestError("Unable to get Ethernet controllers. status: %s,"
                                   "stdout: %s." % (status, output))
    for pci in output.split():
        _, output = utils_misc.cmd_status_output("lspci -v -s %s" % pci,
                                                 shell=True,
                                                 session=session)
        if re.search("SR-IOV", output):
            pf_driver = re.search('driver in use: (.*)', output)[1]
            tmp_info = {'driver': pf_driver, 'pci_id': '0000:%s' % pci}

            iface_name = get_iface_name('0000:%s' % pci, session=session)

This code work when command "lspci |awk '/Ethernet/ {print $1}'" return pcie bus with short format like 02:00.0 Ethernet ... mean domain numbers are omitted since they are all equal to zero!
but, on my system return output with the domain numbers are highlighted.
eg:

lspci  | grep Ethernet
0000:01:00.0 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx]
0000:01:00.1 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx]

I suggest using -D in command lspci and remove prefix 0000:

Thanks,
