If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 76f1cf591d279492646ae1b10d54e4b490bc9167 Author: Alexander Lobakin <alobakin@xxxxxxxxxxx> Date: Tue Jun 23 16:51:33 2020 +0300 net: qed: fix excessive QM ILT lines consumption [ 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.
