-Currently, only "RSS hash" is force enabled
-so that the backend hardware device calculated hash values
-could be shared with applications.
-But for RSS, there is no such API to config RSS hash function or RETA table.
-So, limited RSS is supported only with default config/setting.
+GVE RSS can be enabled and configured using the standard interfaces. The driver
+does not support querying the initial RSS configuration.

+The RSS hash key must be exactly 40 bytes, and the redirection table must have
+128 entries. The RSS hash key must be configured before the redirection table
+can be set up.
