It is better to avoid fixing the packet size here.

- For ssif, get it from "get capabilities" command. If BMC supports only single-part read/write, this size exceeds BMC capability

- For kcs, I don't see the limitation

I think limiting the size here is unsuitable, applications that use this protocol should check the size themselves

I don’t know what “Oen” means. Should it be “Oem” or “IANA” number?

And this number can be configured, other OEMs will have their own number.

This number should be provided by drivers that consume this protocol
This commit uses OpenBMC IPMI blob commands defined in https://github.com/openbmc/phosphor-ipmi-blobs which are fixed numbers. So, no problem to have fixed definition.

+# IPMI Blob Transfer Interface Driver
+
+This DXE module is a UEFI implementation of the Phorphor Blob Transfer Interface defined in OpenBMC
+https://github.com/openbmc/phosphor-ipmi-blobs
+
+## NVIDIA's OpenBMC implements this interface as a protocol, allowing UEFI and BMC to transfer blobs over IPMI.
+
+### Usage:
+Any DXE module that wishes to use this protocol should do the following:
+1) The module should have a dependency on gEdkiiIpmiBlobTransferProtocolGuid in its inf "Depex" section
+2) The module should list gEdkiiIpmiBlobTransferProtocolGuid in its inf "Protocol" section
+3) The module's entry point should do a LocateProtocol on gEdkiiIpmiBlobTransferProtocolGuid
+
+### A sample flow of protocol usage is as follows:
+1) A call to IpmiBlobTransferOpen ()
+2) Iterative calls to IpmiBlobTransferWrite
+3) A call to IpmiBlobTransferClose ()
+
+### Unit Tests:
+IpmiBlobTransferDxe/UnitTest/ contains host based unit tests of this implementation.
+Any changes to IpmiBlobTransferDxe should include proof of successful unit tests.
+
+### Debugging
+To assist in debugging any issues, change BLOB_TRANSFER_DEBUG to 1
