Subject: migration: Properly apply migration compression level parameters
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b4014a2bf57ce08e2f6458cd82e9f968facf25c8;p=qemu.git

migration: Properly apply migration compression level parameters

Some glue code was missing, so that using `qmp_migrate_set_parameters`
to set `multifd-zstd-level` or `multifd-zlib-level` did not work. This
commit adds the glue code to fix that.
