Subject: [EXTERNAL] MS-SMB2 NETWORK_INTERFACE_INFO Response for ROCEv1 and Infiniband

Hi DocHelp,

following the discussion at SambaXP I'm wondering how
SMB3 over SMB-Direct over ROCEv1 or Infiniband can work...

MS-SMB2 2.2.32.5 NETWORK_INTERFACE_INFO Response only specifies IPv4 or IPV6 as possible address families.
But only ROCEv2 (on ip/udp) and iWarp (on ip/tcp) work over ip networks.

Can you please clarify this as various discussions and older SDC talks talk about Infiniband being supported for SMB-Direct and SMB.

Thanks!
