Subject: [NIU]: More BMAC alt MAC address fixes.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fa907895b7b776208a1406efe5ba7ffe0f49f507;p=linux-beck.git

[NIU]: More BMAC alt MAC address fixes.

From: Matheos Worku <Matheos.Worku@Sun.COM>

1) niu_enable_alt_mac() needs to be adjusted so that the mask
   is computed properly for the BMAC case.

2) BMAC has 6 alt MAC addresses available, not 7.
