Can you provide Packet Data size setting up to 15500?
seems to be limited now at 1408

Hi!

Unfortunately,this is impossible for now, but we will definitely add it in future release.

FCoE is dead. There would be no updates.

Hello Anton,

I think problem with FCoE initiator was resolved by someone else..

If you have no more interest in supporting FCoE , maybe you can open source code

for us to fix and use.

Anyway , thank you

Keeping in mind VMware is concentrating on object storage (feeding storage directly to VM bypassing block level and file system) and Microsoft does SMB3 and sees SMB3 as a future of a VM storage we can technically consider FCoE as a dead cow now. I don't know will we open our initiator and open source it (I doubt...) but we're definitely not going to invest anything into FCoE so far.
