false-positive errors with pyroute2 0.7.6

[gthiemonge]

Bug description

When using pylint with pyroute2 0.7.6, it detects false-positive issues:

The following code is valid pyroute2 code:

import sys

import pyroute2

with pyroute2.IPRoute() as ipr:
    idx = ipr.link_lookup(ifname=sys.argv[1])[0]
    link = ipr.get_links(idx)[0]
    print(link)

But with the pyroute2 0.7.6 release, pylint detects some false-positive problems:

$ pip install pyroute2 pylint

$ pylint test_pyroute.py
************* Module test_pyroute
test_pyroute.py:7:11: E1136: Value 'ipr.get_links(idx)' is unsubscriptable (unsubscriptable-object)
test_pyroute.py:7:11: E1121: Too many positional arguments for method call (too-many-function-args)

https://github.com/svinota/pyroute2/blob/master/pyroute2/iproute/linux.py#L434

the get_links function takes positional arguments and returns a list.

(Note that pylint works fine with pyroute2 0.7.5)

Command used

pylint test_pyroute.py

Pylint output

************* Module test_pyroute
test_pyroute.py:7:11: E1136: Value 'ipr.get_links(idx)' is unsubscriptable (unsubscriptable-object)
