[ Upstream commit 06c59d97f63c1b8af521fa5aef8a716fb988b285 ]
The name len field of the CMD_OPEN packet is only 16-bits and the upper
16-bits of "param2" are a different "prio" field, which can be nonzero in
certain situations, and CMD_OPEN packets can be unexpectedly dropped
because of this.
Fix this by masking out the upper 16 bits of param2.
