wifi: mt76: mt7915: add dummy HW offload of IEEE 802.11 fragmentation
[ Upstream commit f2cc859149240d910fdc6405717673e0b84bfda8 ]
Currently, CONNAC2 series do not support encryption for fragmented Tx frames.
Therefore, add dummy function mt7915_set_frag_threshold() to prevent SW
IEEE 802.11 fragmentation.
