It does show whether interface supports RSS or RDMA in the channel list for every session (and whether that interface is 'CONNECTED' for that session). See below example from his sample /proc/fs/cifs/DebugData output (although this part did not change with his patch) 4) Speed: 1000000000 bps Capabilities: rss IPv4: 10.229.158.38 [CONNECTED] Thanks, Steve
