Drivers: hv: Support the newly introduced KVP messages in the driver
Support the newly defined KVP message types. It turns out that the host pushes a set of standard key value pairs as soon as the guest opens the KVP channel. Since we cannot handle these tuples until the user level daemon loads up, defer reading the KVP channel until the user level daemon is launched. Signed-off-by: K. Y.
