net: ena: fix incorrect default RSS key
[ Upstream commit 0d1c3de7b8c78a5e44b74b62ede4a63629f5d811 ]
Bug description:
When running "ethtool -x <if_name>" the key shows up as all zeros.
When we use "ethtool -X <if_name> hfunc toeplitz hkey <some:random:key>" to
set the key and then try to retrieve it using "ethtool -x <if_name>" then
we return the correct key because we return the one we saved.
Bug cause:
We don't fetch the key from the device but instead return the key
that we have saved internally which is by default set to zero upon
allocation.
Fix:
This commit fixes the issue by initializing the key to a random value
using netdev_rss_key_fill().
