From 9d3679fe0f30b5a4c1ae6303611c9f2bbeb9961d Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Sun, 19 Apr 2020 23:16:55 +0200 Subject: [PATCH] r8169: inline rtl8169_make_unusable_by_asic Inline rtl8169_make_unusable_by_asic() and simplify it: - Address field doesn't need to be poisoned because descriptor is owned by CPU now - desc->opts1 is set by rtl8169_mark_to_asic() and rtl8169_rx_fill(), therefore we don't have to preserve any field parts.
