It's my first topic on forum...
I'm using a few Sophos devices like XG105w XG115w and little older Cyberoam CR15wING without any issue, so I thought that Sophos XGS107 is capable to work under OWRT as well. I was very disappointed when after M2 SSD flash, OWRT running without any network interface! I installed additional software like pci-utils to see which network controller is on board - found:
03:00.0 Ethernet controller: Marvell Technology Group Ltd. Device 7080
but I didn't found information about driver I should use.
Moreover, I tried to install Debian 12, newest Ubuntu Server, OPnsense and no one OS recognized network controller.
Has anyone advice how to add network to OWRT with this exotic network controller?
lspci -nn (or even better lspci -knn on Debian) should tell you which kernel modules are needed for this hardware, OpenWrt only preinstalls a handful of the most common ones (the less common ones would need to be installed).
Well, no need to install it again, if you already removed it - as mentioned, "lspci -nn" on any linux would do (you can always use lspci -knn as well, -knn just won't tell much over -nn, if the required kernel module isn't already installed).
Actually I checked lspci under OWRT, Debian I used only in installer phase (and see that it is not capable to recognize network controller). So I'm during full installation of Debian process just now to have fully working OS for tests
EDIT:
lspci -knn result:

So only Device ID we will see - I tried yesterday found HW assigned to this ID but without success...
Not likely. The 1x7 devices appear to have undergone a major design change. The 1x5 and 1x6 devices were built on Intel network controllers. The 1x7 devices have a Marvell switch (which, incidentally, shows in your lspci listing). That switch operates as a router unto itself (it has its own ARM processor), and the main device must be able to give it explicit operating instructions.
Netgate has a device incorporating a Marvell switch (the 7100, I believe), and they had to write a whole bunch of new code to make the switch work with pfSense Plus. That code was specific to one particular model in the Prestera family of switches and exists only within the proprietary pfSense Plus and not in the open-source pfSense CE.
One time I have encountered a similar switch before was on a Barracuda F180 (see this thread). On that occasion, it turned out that absent explicit direction, the switch works as a dumb switch (i.e., as if it were a single Ethernet port with an external dumb switch connected to it). The F180, however, has other ports in addition to those in the switch, so this is workable. In your case, when all available ports are in the switch, I doubt it is possible to make the router work properly without a driver for the switch. And I am not aware of any such driver forthcoming. I'd love to be wrong on this, but I don't think I am...
Thanks for detailed explanation. The switch is totally dead, not working as dumb switch, so you probably have right. It's very pity because this appliance is totally unusable with original software... expensive toy. I saw similar solution in industrial VPX/SoSA switches witch additional middle-ware layer for communication with independently switch. I hope 1x7 will be more popular in the future and somebody will be able to use it. Temporarily I bought XG106 which is more flexible
Up to 4 ports, you can usually expect vendors to use dedicated ethernet cards per port, beyond that, you usually find some kind of switch - and as NC1 pointed out, this makes stuff really complicated…
Until recently, Sophos had dedicated Intel controllers even on eight- and nine-port models (125 / 135). My guess is, Marvell is undercutting Intel on price while offering comparable performance and greater potential for offloading (there's a whole extra processor built into the switch), so manufacturers buy into Marvell's offerings despite having to put extra effort into software development.
I wonder whether Marvell would eventually consider contributing a driver for those switches (possibly non-free) to Linux...
