The first patch presents a work-around for the TX software time stamping fallback problem cited in cd4d8fdad1f1. The idea is to add two inline functions into each MAC driver. The functions will act as hooks for current (and possible future) time stamping needs, once they are placed correctly within each MAC driver. 2. The other patches prepare the way for PHY drivers to offer time stamping. I am preparing a new round of patches for PTP support, but it will require the changes in this patch set in order to function. Thus I would like to have this patch set reviewed (and hopefully merged) in order to go forward. Thanks, Richard * Patch ChangeLog ** v2 Removed the CONFIG option for the driver hooks. Richard Cochran (4): net: add driver hooks for time stamping. phylib: add a way to make PHY time stamps possible. phylib: preserve ifreq parameter when calling generic phy_mii_ioctl() phylib: Allow reading and writing a mii bus from atomic context. drivers/net/arm/ixp4xx_eth.c | 3 +- drivers/net/au1000_eth.c | 2 +- drivers/net/bcm63xx_enet.c | 2 +- drivers/net/cpmac.c | 5 +-- drivers/net/dnet.c | 2 +- drivers/net/ethoc.c | 2 +- drivers/net/fec.c | 2 +- drivers/net/fec_mpc52xx.c | 2 +- drivers/net/fs_enet/fs_enet-main.c | 3 +- drivers/net/fsl_pq_mdio.c | 4 +- drivers/net/gianfar.c | 2 +- drivers/net/macb.c | 2 +- drivers/net/mv643xx_eth.c | 2 +- drivers/net/octeon/octeon_mgmt.c | 2 +- drivers/net/phy/mdio_bus.c | 45 ++++++++++++++++++--- drivers/net/phy/phy.c | 8 +++- drivers/net/sb1250-mac.c | 2 +- drivers/net/sh_eth.c | 2 +- drivers/net/smsc911x.c | 2 +- drivers/net/smsc9420.c | 2 +- drivers/net/stmmac/stmmac_main.c | 22 ++++------- drivers/net/tc35815.c | 2 +- drivers/net/tg3.c | 2 +- drivers/net/ucc_geth.c | 2 +- drivers/staging/octeon/ethernet-mdio.c | 2 +- include/linux/phy.h | 24 ++++++++++- include/linux/skbuff.h | 65 ++++++++++++++++++++++++++++++++ net/Kconfig | 11 +++++ net/dsa/slave.c | 3 +- 29 files changed, 175 insertions(+), 54 deletions(-)
