Linux kernel source tree

In the previous implementation, when multiple xsk sockets were associated with a single xsk_buff_pool, a situation could arise where the xsk_tx_list maintained data at the front for one xsk socket while starving the xsk sockets at the back of the list. This could result in issues such as the inability to transmit packets, increased latency, and jitter. To address this problem, we introduce a new variable called tx_budget_spent, which limits each xsk to transmit a maximum of MAX_PER_SOCKET_BUDGET tx descriptors. This allocation ensures equitable opportunities for subsequent xsk sockets to send tx descriptors. The value of MAX_PER_SOCKET_BUDGET is set to 32.

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.
