Due to an issue in Take 117, during the installation of any higher Take of R77.30 Jumbo Hotfix Accumulator, the upgrade of "mlx01" RPM fails.
This causes the mlx_compat and mlx5_core drivers for 40 GbE fiber cards to be removed from the appliance (from /lib/modules/$(uname -r)/kernel/drivers/addon/mlx01/).
As a result, traffic is not able to pass through 40 GbE fiber cards.
