@emilazy:matrix.orgemily right. I think both the cheapo Realtek stuff and mlxsw at least don't need userspace blobs 13:50:03
@emilazy:matrix.orgemilyAIUI from reading LKML posts, the Broadcom switch situation is that there's an "upstream" driver that basically just acts as a very dumb pipe between proprietary userspace tools and the switch ASIC13:50:24
@emilazy:matrix.orgemilyso it's not quite what I'd consider a native Linux networking experience13:50:40
@hexa:lossy.networkhexaor more like an sn201013:50:47
@hexa:lossy.networkhexaso not exactly new, but still not worth abandoning 🙂 13:51:37
@hexa:lossy.networkhexawe installed some debian to it and ran bird 1.6 probably13:51:50
@hexa:lossy.networkhexait was limited to 30k routes in hardware13:52:03
@mr.defenestrator:matrix.orgMr. Defenestrator Yea that's kinda the case with broadcom ASICs. Mellanox switches have the best open source module imo. There may be some opportunity with MikroTik whatever in that price range, but I don't touch that stuff.  14:10:10
@mr.defenestrator:matrix.orgMr. Defenestrator You should buy not only the switch, but get a colo and start a NixOS based network shop ;) 14:11:46
@mr.defenestrator:matrix.orgMr. Defenestrator
In reply to @hexa:lossy.network
it was limited to 30k routes in hardware
30k is plenty for that tier of switch IMO. If you have a Linux based BGP already, you could even do route filtering based off your flows and run a "digested" full table. I do that in production with Arista SRD
14:16:03
@mr.defenestrator:matrix.orgMr. Defenestrator If you really like extracting maximal hardware value. 14:16:05
@emilazy:matrix.orgemilyI thought people liked MiktroTik for running the actual vendor stuff but that mainline Linux wasn't really an option. could be wrong though15:27:44
@k900:0upti.meK900Usually the case yeah15:28:06
@emilazy:matrix.orgemilyfeel like I've fallen down enough of a rabbit hole already for now :)15:28:08
@k900:0upti.meK900Though Mikrotik hardware is also fairly commodity15:28:13
@emilazy:matrix.orgemilywhat kind of switch chips do they put in them?15:28:44
@emilazy:matrix.orgemilyI thought it was custom stuff but maybe I'm wrong15:28:54
@k900:0upti.meK900Usually Marvell or Realtek stuff15:29:58
@emilazy:matrix.orgemilyhm.15:30:34
@emilazy:matrix.orgemilyAIUI the Realtek chip that OpenWrt does can actually be operated by an external CPU15:30:52
@emilazy:matrix.orgemilyas in it can be a SoC with a MIPS processor, but it can also just be a "dumb" switch that you have an ARM chip talking to or something.15:31:05
@emilazy:matrix.orgemilyI believe that nobody has implemented support for that in OpenWrt/mainline, but if there's a MikroTik thing with an AArch64 CPU and that Realtek chip it could be interesting…15:31:29

@uep:matrix.orgueprtl8367 seems to be the only realtek one they use recently01:45:32
@uep:matrix.orguepthere are some qualcomm (arm) and mediatek (mmips) ones with soc and small switch on the same chip01:46:23
@uep:matrix.orguepeverything that's a serious switch is marvell01:46:58
@hexa:lossy.networkhexa(within the openwrt ecosystem)01:48:15
@emilazy:matrix.orgemilyhow can I find these things? when I go to https://toh.openwrt.org/?view=network and sort by SFP+s, very little shows up. I've seen that other listings don't have stuff in that field but searching SFP in the net comments also doesn't turn up much13:24:59
@emilazy:matrix.orgemilyI'm interested in everything OpenWrt can run that has more than a handful of 10 Gbit/s SFP+13:25:21
@emilazy:matrix.orgemilyhttps://openwrt.org/docs/techref/hardware/soc/soc.marvell mostly talks about GbE (I guess the page seems fairly old)13:26:09
