It works really well with 19.07.0 version in all areas except it's WAN->LAN routing performance is sub-optimal: I'm getting only ~500Mpbs of my 1gpbs link (no QoS, etc) where my other router (Netgear R6300V2 with FreshTomato 22019.4) is able to achieve ~940Mbps (with CTF enabled). I read the whole story about flow offloading and hardware NATs and was hoping that enabling 'software flow offloading' would help. However it seems to have no effect at all.
I'm aware of flow offloading for certain ramips and ar71xx/ath79 boards, but not for any Broadcom targets. The github link you shared does not seem to talk about offloading either at first glance, nor does the OpenWrt wiki entry.
Long story short: Broadcom doesn't care about FOSS - which is particularly visible in their wireless drivers, but also translates in other areas.
I was referring to software flow offloading, which is a kernel feature, and doesn't need any hardware support, afaik. With 2x1.4GHz ARM cores it should handle 1gbps link decently; for some reason it doesn't.
p.s. wireless performance is completely irrelevant in this case as I'm testing using wired connections only; besides, wifi drivers situation is not that bad anymore, latest firmware blobs allow 160Mhz and DFS channels
Could you please share the exact procedure for flashing the trx file to the router with default firmware? I also want to try openwrt on this hardware but have read some users complaints at the chinese forums about the 5ghz transmission flaws. Have you tried using the wifi continuously and if yes - what is your impression so far besides the slow WAN to LAN performance?
Hi, can you please share your setup in more details (like where did you get the brcmfmac4366-pcie.bin ; i was planning to use the ones from https://github.com/Hill-98/phicommk3-firmware).
I got a k3 a while ago but it was dead (no serial), just yesterday I managed to soldier a spi and put CFE on it so i can fix the nand - seems ok now (still in bits but with 19.07.3).
I have this topic - https://forum.openwrt.org/t/phicomm-k3-thoughts maybe we can merge them and put some structure into it, i will post some photos of the debricking process. There is tons of info on right...cn but even with the translator it is hard to understand and lots of it is hidden because i can't reg.
I extracted driver blob from the latest Asus firmware. There is also one (same) in the right.cn forum discussing 160mhz channel. I only replaced driver, added irqbalance, turned off GRO and removed dfs from reg db. That's basically it. Driver txpower for 5ghz should be around 23-25.
Different chipset... Easy to test though. It seems like optimizations in kernel made to speed up 25gpbs+ links are actually hurting performance of slow links with slow CPUs and/or poorly supported switches.
