Linux kernel source tree
30f253f8d9
With End-of-Packet padding (EOP) set, the chip will disable Relaxed Ordering (RO) of TPA data packets. A TPA segment with EOP set will be padded to the next cache boundary and can potentially overwrite the beginning bytes of the next TPA segment when RO is enabled on 5760X. To prevent that, the chip disables RO for TPA when EOP is set. To take advantge of RO and higher performance, do not set EOP on 5760X chips when TPA is enabled. Define a proper RX_BD_FLAGS_AGG_EOP constant to make it clear that we are setting EOP.

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.
