Subject: [PATCH 5.7 112/163] net: ethernet: ti: am65-cpsw-nuss: fix ale parameters init

From: Grygorii Strashko <grygorii.strashko@...com>

[ Upstream commit 2074f9eaa58795a99e9da61c10f93180f810cfd6 ]

The ALE parameters structure is created on stack, so it has to be reset
before passing to cpsw_ale_create() to avoid garbage values.
