Subject: [PATCH] sfc: disable RXFCS and RXALL features by default
References: bsc#1012628
Patch-mainline: 6.3.4
Git-commit: 134120b066044399ef59564ff3ba66ab344cfc5b

[ Upstream commit 134120b066044399ef59564ff3ba66ab344cfc5b ]

By default we would not want RXFCS and RXALL features enabled as they are
mainly intended for debugging purposes. This does not stop users from
enabling them later on as needed.
