'TCP segmentation offload checksum offload'. It might be better to call it tcp_seg_offload. It might also be good to specify the direction, because interface may technically support Tx, but not support Rx offload for the same thing. So, maybe tx-ip-csum-offload, ..., tx-tcp-seg-offload ? You had something very similar in v9. I'm not sure about underscores vs dashes. I'd like dashes, but some other status fields are reported with underscores, so I don't know.

I don't have a preference other than consistency.

I personally like more when use-facing names and options are using dashes. Underscores are less user-friendly. (Database automatically converts one to another in table/column names, for example.) Let's keep upderscores for now. The global change would be out of scope of this patch set. Best regards, Ilya Maximets.
