|
|
* 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.
