Subject[PATCH 4.14 48/78] net: qed: fix excessive QM ILT lines consumption
Date
From: Alexander Lobakin <alobakin@marvell.com>

[ Upstream commit d434d02f7e7c24c721365fd594ed781acb18e0da ]

This is likely a copy'n'paste mistake. The amount of ILT lines to
reserve for a single VF was being multiplied by the total VFs count.
This led to a huge redundancy in reservation and potential lines
drainouts.

Fixes: 1408cc1fa48c ("qed: Introduce VFs")
