I have not checked Fedora nor RHEL-7.0 Beta, but they are likely to have the same issue, it should be checked and cloned if it is the case. Wouldn't it be even nicer if each vf reported its parent pf? It seems that currently we must depend on the iface naming convention to do this mapping, or go /sys/class. @Danken: maybe something like "physfn eth1". (In reply to Dan Kenigsberg from comment #3) > Wouldn't it be even nicer if each vf reported its parent pf? That's a good idea, better than putting all the vf on the same line with the parent interface. Wile I agree with the opinion that VF interfaces should list which physical one they belong to, I don't think this belongs to this ticket. A quick research shows that the kernel exports a list of virtual functions for the physical interface, and iproute reflects just that. So changing the way things are presented might need some preliminary kernel work. I'll clone this ticket into an RFE one to keep me reminded to investigate further. This ticket is about the bug in output formatting, which is indeed present and valid. Patch fixing this sent upstream: http://marc.info/?l=linux-netdev&m=144499191904348&w=2 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem:In the description of the '-o' switch for iproute's 'ip' tool, it says that the entries should be kept in one line escaping the end of lines with '\'. However, when a machine has an intel's sr-iov device configured with several virtual functions, the contract is broken (breaking machine parse-ability). Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. Configure an SR-IOV capable machine with several vfs (this report is with devices using the modules igb and igbvf for the VFs). 2. ip -o link show Actual results: 2: p1p1: <BROADCAST,MULTICAST> mtu
