Saeed Mahameed says: ==================== This patch series contains various fixes, additions and improvements to mlx5 software steering. Patch 1: adds support for REMOVE_HEADER packet reformat - a new reformat type that is supported starting with ConnectX-6 DX, and allows removing an arbitrary size packet segment at a selected position. Patches 2 and 3: add support for VLAN pop on TX and VLAN push on RX flows. Patch 4: enables retransmission mechanism for the SW Steering RC QP. Patch 5: does some improvements to error flow in building STE array and adds a more informative printout of an invalid actions sequence. Patch 6: improves error flow on SW Steering QP error. Patch 7: reduces the log level of a message that is printed when a table is connected to a lower/same level destination table, as this case proves to be not as rare as it was in the past. Patch 8: adds missing support for matching on IPv6 flow label for devices older than ConnectX-6 DX. Patch 9: replaces uintN_t types with kernel-style types. Patch 10: allows for using the right API for updating flow tables - if it is a FW-owned table, then FW API will be used. Patch 11: adds support for 'ignore_flow_level' on multi-destination flow tables that are created by SW Steering. Patch 12: optimizes FDB RX steering rule by skipping matching on source port, as the source port for all incoming packets equals to wire. Patch 13: is a small code refactoring - it merges several DR_STE_SIZE enums into a single enum. Patch 14: does some additional refactoring and removes HW-specific STE type from NIC domain. Patch 15: removes rehash ctrl struct from dr_htbl struct and saves some memory. Patch 16: does a more significant improvement in terms of memory consumption and was able to save about 1.6 Gb for 8M rules. Patch 17: adds support for update FTE, which is needed for cases where there are multiple rules with the same match. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
