Subject: Change the libnetlink function used to query link statistics to match iproute2's... 
X-Git-Tag: collectd-5.0.5~1^2~12
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=696a7c67a5b4bdebfed107c2792c2c66458a0821;p=collectd.git

Change the libnetlink function used to query link statistics to match iproute2's behavior and thus not trip on the kernel's new parsing of optional attributes for RTM_GETLINK.
