    util: allow ignoring SIOCSIFHWADDR when errno is EPERM · 997134fb
    Laine Stump 提交于
    Commit f4ef3a71 made a variation of virNetDevSetMAC that would return
    without logging an error message if errno was set to
    EADDRNOTAVAIL. This errno is set by some SRIOV VF drivers (in
    particular igbvf) when they fail to set the device's MAC address due
    to the PF driver refusing the request. This is useful if we want to
    try a different method of setting the VF MAC address before giving up
    (Commit 86556e16 actually does this, setting the desired MAC address
    to the "admin MAC in the PF, then detaching and reattaching the VF
    netdev driver to force a reinit of the MAC address).
    
    During testing of Bug 1442040 t was discovered that the ixgbe driver
    returns EPERM in this situation, so this patch changes the exception
    case for silent+non-terminal failure to account for this difference.
