[dpdk-dev] [PATCH] fm10k: conditionally disable RSS during device initialization

[Michael Frasca]

If the provided configuration does not call for RSS, then RSS is
explicitly disabled. Without this change, the device continues to
operate under the previous RSS configuration.

Fixes: 57033cdf8fdc ("fm10k: add PF RSS")
