IMHO, it would be more informative to have separate features for TCP, 
UDP and
encapsulated TSO offloads.

Otherwise when a new TSO offload flag is added, it should change all Y to P
(and update PMDs documentation to provide details).

Ideally for all "P" it should be a hyperlink to PMD documentation section
which provides details.
