Hi All, A quick background of what I’m trying to achieve and if possible?
So, having messed about with the TX and RX delay in the U-boot for a Lamobo R1 board, there appears to be some form of effect going on with the network speed measurements. It has been recorded that this board uses the GMAC to talk to the Broadcom BCM53125 PHY - A TX Delay is needed to compensate for differing PCB lengths. My query from looking at the stmmac source code, is what can be the possible causes for a 50% reduction of speed in gigabit mode compared to its little brother of BananaPi A20 (using a realtek PHY)? Is the DMA being used in the stmmac driver for GMAC? Why isnt the rx_coe of bugged_jumbo not being used? (sunxi 3.4 show's it be initiated?) I've noticed on the /proc/softirqs that the RX has large values and TX having small increments? What area should I be looking at to diagnose or debug further? Thanks for any assistance.
