I tested your patch series on Broadcom 40nm set-top box platform that used internal phy. I did not have the exact measurements. but I expect it to improve on the interface-up or link-up time. and I compared the changes roughly from kernel print time. please see below. - before patching [ 1.865126] bcmgenet 10430000.ethernet eth0: Link is Down [ 3.941132] bcmgenet 10430000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx - after patching [ 3.145127] bcmgenet 10430000.ethernet eth0: Link is Down [ 4.189140] bcmgenet 10430000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx > Florian Fainelli (6): > net: bcmgenet: Remove excessive PHY reset > net: bcmgenet: Use correct dev_id for free_irq > net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up() > net: bcmgenet: Determine PHY type before scanning MDIO bus > net: bcmgenet: Delay PHY initialization to bcmgenet_open() > net: bcmgenet: Remove init parameter from bcmgenet_mii_config > > drivers/net/ethernet/broadcom/genet/bcmgenet.c | 33 +++++----- > drivers/net/ethernet/broadcom/genet/bcmgenet.h | 5 +- > drivers/net/ethernet/broadcom/genet/bcmmii.c | 84 ++++++++++++-------------- > 3 files changed, 59 insertions(+), 63 deletions(-) > > -- > 2.1.0 > -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
