Alex,
I loaded mlx5 driver with and without these series. The report in dmesg is now missing. From what I understood, the status should be reported at least once, even if everything is in order. We need this functionality to stay.

net-next (dmesg output for 07:00.0):
[270498.625351] mlx5_core 0000:07:00.0: firmware version: 14.22.4020
[270498.632130] mlx5_core 0000:07:00.0: 63.008 Gb/s available PCIe bandwidth (8 GT/s x8 link)
[270499.169533] (0000:07:00.0): E-Switch: Total vports 9, per vport: max uc(1024) max mc(16384)
[270499.182358] mlx5_core 0000:07:00.0: Port module event: module 0, Cable plugged

net-next + patches (dmesg output for 07:00.0):
[ 331.608472] mlx5_core 0000:07:00.0: firmware version: 14.22.4020
