It's not about times (multiple occurences of an event) but about the duration of a time interval. Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> --- Documentation/networking/phy.rst | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

Due to this design decision, a 1.5ns to 2ns delay must be added between the clock line (RXC or TXC) and the data lines to let the PHY (clock -sink) have enough setup and hold times to sample the data lines correctly. The +sink) have a large enough setup and hold time to sample the data lines correctly. The PHY library offers different types of PHY_INTERFACE_MODE_RGMII* values to let the PHY driver and optionally the MAC driver, implement the required delay. The values of phy_interface_t must be understood from the perspective of the PHY --
