Long time ago there was a concern about impact of the rapidly developing eswitch offload market(?) on FW stability so a requirement was put forward to *compile out* major unused FW features. Such requirement is no longer in place (or fulfilled) largely due to my support. I wish I could support that out by referring to the OCP NIC SW spec, by it's stuck in "legal review" of one of the vendors for months. I'd like to ask that vendor not to pull up the ladder and let everyone else enjoy access to NIC requirements and recommendations from Meta and Google.
