Here is the summary with links:
  - [v3,1/3] net: mana: Add flex array to struct mana_cfg_rx_steer_req_v2
    https://git.kernel.org/netdev/net-next/c/bfec4e18f943
  - [v3,2/3] RDMA/mana_ib: Prefer struct_size over open coded arithmetic
    https://git.kernel.org/netdev/net-next/c/29b8e13a8b4c
  - [v3,3/3] net: mana: Avoid open coded arithmetic
