Is it really 2.5G SGMII or 2.5G Base-X - iow, which configuration word is permissible at 2.5G speeds for the pp2? We already have 2500BASEX in linux/phy.h, which is the 802.3z compliant 16-bit configuration word rather than the Cisco variant. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up From mboxrd@z Thu Jan 1 00:00:00 1970 From: linux@armlinux.org.uk (Russell King - ARM Linux) Date: Wed, 3 Jan 2018 17:29:48 +0000 Subject: [PATCH net-next 1/6] phy: add 2.5G SGMII mode to the phy_mode enum In-Reply-To: <20180103150830.GB3401@lunn.ch> References: <20171227221446.18459-1-antoine.tenart@free-electrons.com> <20171227221446.18459-2-antoine.tenart@free-electrons.com> <20171228072053.GA27336@lunn.ch> <20171228100656.GF2626@kwain> <91838ce5-a1a8-c41a-36e8-bef7adaf82fd@gmail.com> <20180103143541.GE21727@kwain> <20180103150830.GB3401@lunn.ch> Message-ID: <20180103172948.GG28752@n2100.armlinux.org.uk> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On Wed, Jan 03, 2018 at 04:08:30PM +0100, Andrew Lunn wrote: > > > >>> diff --git a/include/linux/phy/phy.h b/include/linux/phy/phy.h > > > >>> index 4f8423a948d5..70459a28f3a1 100644 > > > >>> --- a/include/linux/phy/phy.h > > > >>> +++ b/include/linux/phy/phy.h > > > >>> @@ -28,6 +28,7 @@ enum phy_mode { > > > >>> PHY_MODE_USB_DEVICE, > > > >>> PHY_MODE_USB_OTG, > > > >>> PHY_MODE_SGMII, > > > >>> + PHY_MODE_SGMII_2_5G, > > > >>> PHY_MODE_10GKR, > > > >>> PHY_MODE_UFS_HS_A, > > > >>> PHY_MODE_UFS_HS_B, > > > >> > > > >> There was a discussion maybe last month about adding 2.5G SGMII.
