This patch series backports MCTP over USB to the open-bmc 6.12 branch.
The commit series is mostly the base support, with the addition of bindings
via IFLA attributes. No out of tree fixes were added in this patch series.
The base for base support of the MCTP USB transport device were taken
with the fixes from 6.6
