Subject: Program the firmware setup stuff with the current hardware setup:
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=085a5ea64a369b01de22c8f47eb9e512c70d4e02;p=people%2Fjulieng%2Ffreebsd.git

Program the firmware setup stuff with the current hardware setup:

* Do 1T1R for now, until we read the config out of ROM and use it.
* Disable turbo mode, I dunno what this is, but the linux drivers
  have this disabled.
* Set the firmware endpoints to what we read from USB.

Tested:

* RTL8712 cut 3, STA mode
