[PATCH v2 0/5] Fix prestera driver fail to probe twice

[Elad Nachman]

From: Elad Nachman <enachman@xxxxxxxxxxx>

Fix issues resulting from insmod, rmmod and insmod of the
prestera driver:

1. Call of firmware switch HW reset was missing, and is required
   in order to make the firmware loader shift to the correct state
   needed for loading the next firmware.
2. Time-out for waiting for firmware loader to be ready was too small.
3. memory referencing after freeing
4. MAC addresses wrapping
5. Missing SFP unbind (phylink release) of a port during the port release.

v2:
  1) Split first patch to firmware call for switch HW reset and to
     increasing of firmware loader wait to be ready timeout
  2) Explain why is switch HW reset call to the firmware required
     before shutdown in commit message, and fix wording
  3) Use a simpler bitwise-and on the last byte of the base MAC address
     instead of randomizing again the entire MAC address.
     reflect that change in the commit message, and explain why it is
     needed (switch HW implementation requirement).
  4) Add Fixes Tags to all commits.
  5) For timeout enlargement commit, fix wording in comment and move
     timeout units to milliseconds.
  6) Add Tested-By tags.
  7) Add patch to call prestera_port_sfp_unbind() from
     prestera_destroy_ports() in order to release phylink.
