Series | net: phy: Add ability to debug RGMII connections | expand |
From: Florian Fainelli <f.fainelli@gmail.com> Date: Tue, 15 Oct 2019 15:49:51 -0700 > This patch series is primarily intended to reduce the amount of support > involved with bringing up RGMII connections with the PHY library (or > PHYLINK) for that matter. The idea consists in looping back a packet we > just crafted and check whether it did came back correctly, if that is > the case, we are good, else we must try configuring the PHY for > different delays until it either works or we bail out. > > As indicated in the commit message, future improvements could probably > be done in order to converge faster on the appropriate configuration. > This is intended to be PHY centric, and we are not playing with delays > on the MAC side other than through the parsing of the phydev->interface. > > The typical output would look like this: > > [ 62.668701] bcmgenet 8f00000.ethernet eth0: Trying "rgmii-txid" PHY interface > [ 62.676094] bcmgenet 8f00000.ethernet eth0: Determined "rgmii-txid" to be correct > > Feedback highly welcome on this! Looks like there was some feedback, please address. Thank you.
