Hello,
I am now writing a giga ethernet driver, currently a GLDV2 driver. I am thiking about whether I should enable VLAN for my GLDv2 driver or upgrade to GLDv3 first then enable VLAN. I found some GLDV2 drivers use [b]gldm_send_tagged[/b] to send VLAN packets, but most GLDV2 do not support VLAN.
I couldnot find any man page for this API. Is VLAN not fully supported at GLDv2? I am wondering the VLAN capabilities(what can it do, what can not) in GLDV2 and GLDV3. Any improvement in GLDV3?
Can someone give an explaination?
VLAN is supported in GLDv2, but is not a documented API.
I'd wait for GLDv3 before doing VLAN. Its vastly simpler. (All you
have to do is support full MTU size frames.)
With clearview, even your old GLDv2 driver without explicit VLAN support
will work with VLAN, just the MTU will slightly smaller (1496 instead of
1500 bytes.)
