[dpdk-dev] [PATCH] net/ice: fix initialization of RSS look-up table

[Zhang,Alvin]

From: Alvin Zhang <alvinx.zh...@intel.com>

RSS look-up table initialization is done incorrectly due to divide-by-zero
error.
Add a check to rx-queue count.

Fixes: 50370662b727 ("net/ice: support device and queue ops")
