Subject: [PATCH 0/7] introduce mt76-connac dependency in mt7915 driver

Introduce mt76-connac module dependency in the mt7915 driver and remove
duplicated mcu code.

Lorenzo Bianconi (7):
mt76: mt7915: rely on mt76_connac_mcu_alloc_sta_req
mt76: mt7915: rely on mt76_connac_mcu_alloc_wtbl_req
mt76: mt7915: rely on mt76_connac_mcu_add_tlv routine
mt76: connac: move mt76_connac_mcu_get_cipher in common code
mt76: connac: move mt76_connac_chan_bw in common code
mt76: mt7915: rely on mt76_connac_get_phy utilities
mt76: connac: move mt76_connac_mcu_add_key in connac module

From what I can tell, the broadcast muar index should be 0xe for all
chips, not just mt7915. Would make sense to do this in a separate patch
before this one though.

The change from the len assignment to addition was done as a bugfix in
mt7915. I think it's likely that the assignment is buggy in the connac
code as well and should be changed to match mt7915.
