The discussion around Byte Queue Limits (BQL) centers on its availability and implementation in different kernel versions, particularly within systems like Debian, Ubuntu, and others. It appears BQL requires specific driver support—over fifty drivers currently support it, which poses additional steps for users wanting to ensure this feature is enabled. There's also interest in establishing a method to verify BQL support across drivers, possibly via scripts. The ability to utilize BQL is significant for users managing heavy network loads, such as media servers or NAS devices, prompting some to consider hardware and driver compatibility when planning upgrades or new purchases.
