Some mlx5 adapter firmware allows the driver to reset the firmware in the event of an error. When a software reset is issued on any physical function all PFs enter reset state. This is a recoverable condition. The existing recovery flow was designed to allow the recovery of a VF after a PF driver reload. This patch expands the scope of that flow to recover PFs or VFs after a SW reset has been issued. When a software reset is issued the following occurs: 1. The NIC interface mode is set to SW_RESET (7) while the reset is in progress. 2. Once the reset completes the NIC interface mode is set to NIC disabled (1). After the reset has been issued (added in a subsequent patch) the health poll for other functions will detect that the NIC interface state has been set to disabled. This will cause it to enter the existing recovery flow. If the PCI is still working (meaning it doesn't return 0xff on all reads) it means recovery can proceed immediately instead of waiting 60 seconds. The error detetion has also been refactored to avoid incorrect or misleading log messages. Submitted by: slavash@ MFC after: 1 week Sponsored by: Mellanox Technologies |

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
