X-Git-Tag: v3.5-rc1~109^2~422
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=0004299ad41885a0a1fd321715fe7396be17ce35;p=~emulex%2Finfiniband.git

r8169: modify pll power function

Adjust r810x_pll_power_down, r810x_pll_power_up, and r8168_pll_power_up.
Always power up device during rtl_open. For r810x, turn off more power
when the WOL is disabled.
