Resets may occur with or without user interaction. For example, a TX hang or reconfiguration of parameters will result in a reset. During reset, the VSI is freed, freeing any statistics structures inside as well. This would create an issue for the user where a reset happens in the background, statistics set to zero, and the user checks ring statistics expecting them to be populated. To ensure this doesn't happen, accumulate ring statistics over reset. Define a new ring statistics structure, ice_ring_stats. The new structure lives in the VSI's parent, preserving ring statistics when VSI is freed. 1. Define a new structure vsi_ring_stats in the PF scope 2. Allocate/free stats only during probe, unload, or change in ring size 3. Replace previous ring statistics functionality with new structure Signed-off-by: Benjamin Mikailenko <benjamin.mikailenko@intel.com> Tested-by: Gurucharan G <gurucharanx.g@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@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.
