An earlier patch made sure that the queues are not lagging too far behind. This means that iwl_mvm_release_frames should not be called with a head_sn too far behind NSSN. Don't take the risk to change completely the entry condition to iwl_mvm_release_frames, but don't update the head_sn is the NSSN is more than 2048 packets ahead of us. Since this just cannot be right. This means that the scenario described here happened. We are queue 0. Q:0 Q:1 head_sn: 0 -> 2047 head_sn: 2048 Lots of packets arrive: head_sn: 2047 -> 2150 send NSSN_SYNC notification Handle notification from the firmware and do NOT move the head_sn back to 2048 Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
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.
