In some scenarios, the firmware may be stopped before the interface is removed, either due to a crash or because the remoteproc (e.g., MPSS) is shut down early during system reboot or shutdown. This leads to a delay during interface teardown, as the driver waits for a vdev delete response that never arrives, eventually timing out. Example (SNOC): $ echo stop > /sys/class/remoteproc/remoteproc0/state [ 71.64] remoteproc remoteproc0: stopped remote processor modem $ reboot [ 74.84] ath10k_snoc c800000.wifi: failed to transmit packet, dropping: -108 [ 74.84] ath10k_snoc c800000.wifi: failed to submit frame: -108 [...] [ 82.39] ath10k_snoc c800000.wifi: Timeout in receiving vdev delete response To avoid this, skip waiting for the vdev delete response if the firmware is already marked as unreachable (`ATH10K_FLAG_CRASH_FLUSH`), similar to how `ath10k_mac_wait_tx_complete()` and `ath10k_vdev_setup_sync()` handle this case.

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.
