Subject: [NIU]: More BMAC alt MAC address fixes.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fa907895b7b776208a1406efe5ba7ffe0f49f507;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.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.
