2019-11-25RDMA/efa: Store network attributes in device attributesGal Pressman
There's no reason to separate the network attributes from all other device attributes. Embed the fields inside the device attributes and query them all in one function.

2019-06-21RDMA/efa: Be consistent with success flow return valueGal Pressman
The EFA driver is written with success oriented flows in mind, meaning that functions should mostly end with a return 0 statement. Error flows return their error value on their own instead of assuming that the function will return the error at the end. This commit fixes a bunch of functions that were not aligned with this behavior.
