Pull up following revision(s) (requested by msaitoh in ticket #424):
        sys/dev/pci/if_wm.c: 1.545-1.546
  Don't allocate MSI-X interrupt on 82583. 82583 chip has a MSI-X capability in
the PCI configuration space but it doesn't support it. At least the document
doesn't say anything about MSI-X. Fixes PR#52767 reported by
Shinichi Doyashiki.
--
- 82583 supports jumbo frame. Fixes PR#52773 reported by Shinichi Doyashiki.
- Cleanup comment.
