1xRGMII + VLAN1/2

[GoogleCodeExporter]

No problem, just a question...

In a nutshell, what is the benefit of using the -027 w/ 1xRGMII + VLAN1/2 
firmware vs the -027 fw?

Could someone clarify the following statement (from the description of the fw):

"Single RGMII with VLAN1/2 LAN/WAN separation. Complete resolve casual 
WAN<->LAN race packets with HW_NAT usage, but not support ISP VLAN filtering."

ISP VLAN filtering will be support in next build for 1xRGMII.

1xRGMII build is better
- no WAN<->LAN race packets (best WAN/LAN isolation)
- USB read vie Ethernet is faster (used raeth from N65U with PPE speedup TX)

I seen you (Padavan) state there that the RT-N56U_3.0.3.1v-027 (en-ru). 
IPv6+IPv4. Linux kernel 3.0.53. 1xRGMII + VLAN1/2. firmware is better than the 
regular .027 build so I decided to install it on my 56u and I was wondering 
what's the benefit to WAN<->LAN race packets are and is it built into the 
firmware...I mean just install it and that's it or is their a "1xRGMII" setting 
somewhere that I have to configure?

Thanks I just never heard of 1xRGMII + VLAN1/2 since you started incorporating 
it into your firmware and google searches only show me this forum and firmware 
downloads no information to what it all is...

Thanks again

1xRGMII means 
giga-switch to CPU connected via single port. WAN/LAN streams isolated by VLANs

2xRGMII means 
giga-switch to CPU connected via two ports. WAN/LAN streams isolated inside 
GMAC on RT3883/3662. RT3883 cannot support two real independent GMAC - both 
GMAC used common IRQ line and DMA channel. This is not good.

I'm with Crisk (comment #3), there doesn't seem to be a very clear explanation 
as to what the benefit is (it'd be really appreciated if you could add a page 
to the wiki explaining all this stuff in one place). Most Google searches just 
bring me back here, and what little info I can find seems to suggest that these 
features are only useful if you're trying to do some *really* advanced stuff.

What problems occur with WAN<->LAN race packets?
Do we really even need the 1xRGMII/VLAN build if all we have is a typical 
single router/switch home environment?
Do we need to configure a VLAN or anything else to benefit from that build?
How do we even use the RGMII feature, whether it's 1x or 2x (just out of 
curiosity)?

I second the previous comment (#8), I too had to dig a lot trying to understand 
the differences between the two builds.  A wiki page explaining the different 
flavours would be very welcome.
