Subject: net: phy: marvell10g: fix the PHY id mask

From: Antoine Tenart <antoine.tenart@free-electrons.com>


[ Upstream commit 952b6b3b07877419386e719ff20917170e1ce684 ]

The Marvell 10G PHY driver supports different hardware revisions, which
have their bits 3..0 differing. To get the correct revision number these
bits should be ignored. This patch fixes this by using the already
defined MARVELL_PHY_ID_MASK (0xfffffff0) instead of the custom
0xffffffff mask.
