Subject: [PATCH V3 net-next 04/12] net: ena: change default RSS hash function to Toeplitz

From: Arthur Kiyanovski <akiyano@...zon.com>

Currently in the driver we are setting the hash function to be CRC32.
Starting with this commit we want to change the default behaviour so that
we set the hash function to be Toeplitz instead.
