Subbaraya Sundeep says: ==================== octeontx-af2: Fixes for CN10K and CN9xxx platforms This patchset has consolidated fixes in Octeontx2 driver handling CN10K and CN9xxx platforms. When testing the new CN10K hardware some issues resurfaced like accessing wrong register for CN10K and enabling loopback on not supported interfaces. Some fixes are needed for CN9xxx platforms as well. Below is the description of patches Patch 1: AF sets RX RSS action for all the VFs when a VF is brought up. But when a PF sets RX action for its VF like Drop/Direct to a queue in ntuple filter it is not retained because of AF fixup. This patch skips modifying VF RX RSS action if PF has already set its action. Patch 2: When configuring backpressure wrong register is being read for LBKs hence fixed it. Patch 3: Some RVU blocks may take longer time to reset but are guaranteed to complete the reset. Hence wait till reset is complete. Patch 4: For enabling LMAC CN10K needs another register compared to CN9xxx platforms. Hence changed it. Patch 5: Adds missing barrier before submitting memory pointer to the aura hardware. Patch 6: Increase polling time while link credit restore and also return proper error code when timeout occurs. Patch 7: Internal loopback not supported on LPCS interfaces like SGMII/QSGMII so do not enable it. Patch 8: When there is a error in message processing, AF sets the error response and replies back to requestor. PF forwards a invalid message to VF back if AF reply has error in it. This way VF lacks the actual error set by AF for its message. This is changed such that PF simply forwards the actual reply and let VF handle the error. Patch 9: ntuple filter with "flow-type ether proto 0x8842 vlan 0x92e" was not working since ethertype 0x8842 is NGIO protocol. Hardware parser explicitly parses such NGIO packets and sets the packet as NGIO and do not set it as tagged packet. Fix this by changing parser such that it sets the packet as both NGIO and tagged by using separate layer types. ==================== 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.
