[ovs-dev] [PATCH 3/3] rhel: Fix ifup and ifdown after DPDK naming change.
Names like dpdk0 and dpdk1 are not enough to identify a DPDK interface. We could update README.RHEL.rst and add OVS_EXTRA='set Interface ${DEVICE} options:dpdk-devargs=:01:00.0' but a better solution is to add new parameters in the configuration file to explicitly specify the dpdk-devargs.

Now for each interface we need to specify two parameters: the name (it is chosen by the user and it can be arbitrary) and the devargs (most likely the PCI address). With this patch the user enters the names in BOND_IFACES and the devargs in BOND_DPDK_DEVARGS. set -- ${BOND_DPDK_DEVARGS} for _iface in ${BOND_IFACE}; do echo $_iface $1 shift done is a quick and dirty way to iterate through both lists in the same loop. Or maybe we could change the interface to specify in the same list the name and the devargs. Aaron, since you were looking at this as well, do you have any preference on the user interface?

Oh! I did not notice the new "shift". Acked-by: Ben Pfaff ___ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev

I don't have a preference, but I think typically put OVS_ in front of variables in the ifcfg-* files.

I don't understand why this uses "set" then $1.
