Subject: b43: HT-PHY: init: add missing PHY mask/set ops
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=357e24d2d07a2bb5bf706026d1ccf508c56b9b3e;p=openwrt%2Fstaging%2Fblogic.git

b43: HT-PHY: init: add missing PHY mask/set ops

MMIO hacks were used to trick ndis&wl. For example following:
 phy_read(0x0280) -> 0xffff
phy_write(0x0280) <- 0xff3e
***
 phy_read(0x0280) -> 0x0000
phy_write(0x0280) <- 0x003e
was translated to mask 0xff00 and set 0x3e.
