David Wei says: ==================== bnxt_en: implement netdev_queue_mgmt_ops Implement netdev_queue_mgmt_ops for bnxt added in [1]. This will be used in the io_uring ZC Rx patchset to configure queues with a custom page pool w/ a special memory provider for zero copy support. The first two patches prep the driver, while the final patch adds the implementation. Any arbitrary Rx queue can be reset without affecting other queues. V2 and prior of this patchset was thought to only support resetting queues not in the main RSS context. Upon further testing I realised moving queues out and calling bnxt_hwrm_vnic_update() wasn't necessary. I didn't include the netdev core API using this netdev_queue_mgmt_ops because Mina is adding it in his devmem TCP series [2]. But I'm happy to include it if folks want to include a user with this series. I tested this series on BCM957504-N1100FY4 with FW 229.1.123.0. I manually injected failures at all the places that can return an errno and confirmed that the device/queue is never left in a broken state.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
