Instead of using efx_tx_queue_partner(), which relies on the assumption that tx_queues_per_channel is 2, efx_tx_send_pending() iterates over txqs with efx_for_each_channel_tx_queue(). We unconditionally set tx_queue->xmit_pending (renamed from xmit_more_available), then condition on xmit_more for the call to efx_tx_send_pending(), which will clear xmit_pending. Thus, after an xmit_more TX, the doorbell is un-rung and xmit_pending is true. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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 Restructured Text 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.
