![]() zebra uses the SIOCETHTOOL ioctl with the ETHTOOL_GSET command to
fetch the speed of interfaces from the kernel. The only problem is
that ETHTOOL_GSET returns EOPNOTSUPP when the given interface is a
virtual interface. This leads to zebra emitting warnings like this
at startup:
ZEBRA: IOCTL failure to read interface lo speed: 95 Operation not supported
ZEBRA: IOCTL failure to read interface dummy0 speed: 95 Operation not supported
ZEBRA: IOCTL failure to read interface ovs-system speed: 95 Operation not supported
Silence these warnings by ignoring EOPNOTSUPP errors, since we know
they are harmless. This is similar to how we handle EINVAL errors
from the BSD SIOCGIFMEDIA ioctl (commit
