Subject: [PATCH] mlxsw: reg: Extend MGPIR register with new slot fields
|
|
|
|
Extend MGPIR (Management General Peripheral Information Register) with
|
|
new fields specifying the slot number and number of the slots available
|
|
on system. The purpose of these fields is:
|
|
- to support access to MPGIR register on modular system for getting the
|
|
number of cages, equipped on the line card, inserted at specified
|
|
slot. In case slot number is set zero, MGPIR will provide the
|
|
information for the main board. For Top of the Rack (non-modular)
|
|
system it will provide the same as before.
|
|
- to provide the number of slots supported by system. This data is
|
|
relevant only in case slot number is set zero.
