FWIW, we're using those patches on a rather old fork, and they work

But there seems to be a serious throughput limitation for an AST2500
getting data over NCSI. With typical OpenBMC load on CPU we are
limited to about 1.0 MB/s (testing with netcat running on BMC
receiving a file of fixed length with TCP and directing it to
/dev/null), so installation from virtual media is quite slow.

Can you please benchmark your system for comparison? Do you use NCSI
for the management channel?

For the reference, USB mass storage gadget is able to stream data to
the host OS at about 11.5 MB/s.
