Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

|

* the driver should pass the cmng_init_input struct, the port_init function

* will prepare the required internal ram structure which will be passed back
|
|
* to the driver (cmng_init) that will write it into the internal ram.
|
|
*
|
|
* IMPORTANT REMARKS:
|
|
* 1. the cmng_init struct does not represent the contiguous internal ram
|
|
* structure. the driver should use the XSTORM_CMNG_PERPORT_VARS_OFFSET
|
|
* offset in order to write the port sub struct and the
|
|
* PFID_FROM_PORT_AND_VNIC offset for writing the vnic sub struct (in other
|
|
* words - don't use memcpy!).
|
|
* 2. although the cmng_init struct is filled for the maximal vnic number
|
|
* possible, the driver should only write the valid vnics into the internal
|
|
* ram according to the appropriate port mode.
