You can of course use = both ports at the same time, but if you're envisioning something like an = IPoIB version of an Ethernet LAGG I don't think that is supported. If you are using the IB for storage protocols, then active/active = multipathing is one way to utilize the full bandwidth of multiple ports. >> Lastly, is NFS RDMA properly supported on FreeBSD? >=20 > Again not sure. Other people here would likely know. :)
