[PATCH v1] [v1] platform/mellanox: Fix mlxbf-tmfifo not handling all virtio CONSOLE notifictions
From: Shiih-Yi Chen
Date: Mon Aug 14 2023 - 13:54:45 EST
From: shihyic <shihyic@xxxxxxxxxx>
rshim console does not show all entries of dmesg.
Fixed by setting MLXBF_TM_TX_LWM_IRQ for every CONSOLE notification.
